Murchadh Mac Suibhne (died 1267) was a leading member of Clann Suibhne. He was a grandson of the family's eponymous ancestor Suibhne mac Duinn Shléibhe, and a nephew of the family's mid-thirteenth-century representative, Dubhghall mac Suibhne.

During the latter's career, the Scottish Crown sought to extend royal authority into Argyll and the Isles. In the course of this westward drive, Clann Suibhne fell prey to the Stewarts, one of Scotland's most powerful and families. Charter evidence dating to the early 1260s reveals that Dubhghall resigned the Clann Suibhne lordship into the hands of Walter Stewart, Earl of Menteith. Whether this transfer was the result of a military operation against Clann Suibhne is unknown.

The fact that some members of Clann Suibhne were unwilling to subject themselves to Stewart domination is evinced by the record of Murchadh supporting the cause of Hákon Hákonarson, King of Norway, who led a retaliatory campaign to reassert Norwegian authority in 1263. Murchadh played a prominent part in this campaign. He was amongst the Islesmen commanded a detachment of Hákon's fleet into Loch Lomond, where they devastated the Lennox district. Upon the close of the campaign, Murchadh was rewarded the lordship of Arran for his services.

Unfortunately for Murchadh and his family, Scottish power remained unbroken after Hákon withdrew from the region. Scottish forces are reported to have led retaliatory campaigns into the Isles the following year. As such, Murchadh appears to have had little choice but to submit to the Scots. A son of his is certainly recorded to have been kept as a royal hostage.

Although Clann Suibhne's lordship in Argyll appears to have ended by the 1260s, the family was evidently closely associated with the Uí Domhnaill kindred in Ireland. Later generations of Clann Suibhne chieftains certainly commanded gallowglass warriors on behalf of the Uí Domhnaill and other Irish families. Murchadh himself may have met his end pursuing such a career, as he is reported to have died a prisoner of Walter de Burgh, Earl of Ulster in 1267, having been taken prisoner in Connacht.

Ancestry

Murchadh was a son of Maol Mhuire mac Suibhne.Sellar (1971). The latter's father was Suibhne mac Duinn Shléibhe, eponymousCoira (2012) p. 191; Woolf (2005); Dawson (1995) p. 90; Sellar (1971) p. 27. ancestor of Clann Suibhne.McGettigan (2005); Tabraham (2005) pp. 28, 110; Campbell of Airds (2004) p. 183; Roberts (1997) p. 101; Ewart; Triscott; Holmes et al. (1996) p. 518; Argyll: An Inventory of the Monuments (1992) pp. 19, 249 § 119, 258 § 119.

According to the sixteenth-century Leabhar Clainne Suibhne, Murchadh bore the epithet ("the mad"). If this source is to be believed, his father bore the epithet ("the purse"),Nicholls (2007) pp. 91–92; Walsh (1920) pp. 4–5 § 3, 8–9 § 6, 8–9 § 7. and was married to Bean Mhídhe, daughter of Toirdhealbhach Ó Conchobhair.Nicholls (2007) pp. 91–92; Walsh (1920) pp. 4–7 § 3.

There is reason to suspect that these claims are nevertheless erroneous.Nicholls (2007) pp. 91–92. The earliest source to outline Clann Suibhne's descent is the fourteenth-century Book of Ballymote,Nicholls (2007) pp. 91–92; Walsh (1920) pp. xxii, 77, 79. which appears to show that Leabhar Clainne Suibhne has omitted two generations, merging Murchadh and his father with a like-named son and grandson.Nicholls (2007) pp. 91–92; Walsh (1920) p. xxii.

Various Irish annals, such as the fifteenth- to sixteenth-century Annals of Connacht, record that a member of Clann Suibhne named Maol Mhuire was married to Bean Mhídhe, daughter of Toirdhealbhach, son of Ruaidhrí Ó Conchobhair, King of Connacht.Duffy (2013) p. 132 n. 39; Nicholls (2007) p. 92, 92 n. 44; Simms (2007) p. 107; Annála Connacht (2011a) § 1269.6; Annála Connacht (2011b) § 1269.6; Duffy (2007) p. 8; Duffy (2002) pp. 190–191 n. 6. The fact that this source specifically identifies Bean Mhídhe as "the wife" of her husband, in an annal entry outlining her death in 1269, suggests that her husband was still alive at the time.Nicholls (2007) p. 92 n. 44. This in turn suggests that the annal entry refers to the wife of Murchadh's son; and that the epithets and are those of Murchadh's son and grandson.Nicholls (2007) p. 92.

Scottish encroachment in Argyll

During the reign of Alexander II, King of Scotland, the Scots extended royal authority into Argyll and the Isles. In the early 1260s, about a decade after Alexander II's death, his son and royal successor, Alexander III, came of age and took steps to continue his father's westward expansion.Reid (2011); Wærdahl (2011) p. 49; Alexander; Neighbour; Oram (2002) p. 18. As with the previous reign, it was the Stewart family, this time in the person of Walter Stewart, Earl of Menteith, who spearheaded the campaign.Forte; Oram; Pedersen (2005) pp. 255–256; Cowan (1990) p. 122. Evidence of this push is preserved by the record of Clann Suibhne possessions being granted away in the early 1260s.Boardman (2006) p. 15; Forte; Oram; Pedersen (2005) pp. 255–256; Cowan (1990) p. 122; Barrow (1973) p. 373.

For example, on 17 April 1261, Dubhghall, with the consent of his heir Eóin, granted the church of St Colmán Ela (Kilcalmonell) to Paisley Abbey, along with the chapel of St Columba near Skipness Castle.MacDonald, IG (2013) p. 315; Boardman (2007) p. 97; Butter (2007) pp. 84, 84 n. 200, 90; Boardman (2006) pp. 15, 30 n. 34; McDonald (1997) pp. 228, 241; Jennings (1994) p. 143; Argyll: An Inventory of the Monuments (1992) p. 258 § 119; Munro; Munro (1986) p. 87 § 58; Dunbar; Duncan (1971) p. 6; Argyll: An Inventory of the Monuments (1971) p. 178 § 314; Sellar (1971) p. 27; Simpson (1960) p. 12; McKerral (1951) p. 5; Campbell (1911) p. 277; Paul (1909) p. 130; Brown, A (1889) p. 189; Fraser (1888a) pp. 62–63; Lees (1878) p. 70; Origines Parochiales Scotiae (1854) pp. 27, 40; Howson (1841) p. 84; Registrum Monasterii de Passelet (1832) pp. 120–121; Document 3/381/1 (n.d.). Furthermore, a charter of Walter Stewart to Paisley Abbey, dating to 19 January 1262, confirms Dubhghall's grant to the abbey, and states that Dubhghall had earlier granted the lands of Skipness to Walter Stewart himself.Barker (2017); Boardman (2006) p. 30 n. 34; Jennings (1994) p. 143; Argyll: An Inventory of the Monuments (1992) p. 258 § 119; Cowan (1990) p. 122; Easson (1986) p. 149; Munro; Munro (1986) p. 87 § 58; Sellar (1971) p. 27; McKerral (1951) p. 5; Campbell (1911) pp. 277, 278 n. 1; Paul (1909) pp. 130–131; Brown, A (1889) p. 189; Fraser (1888a) p. 63; Fraser (1888b) pp. xxx § 8, 216–217; Origines Parochiales Scotiae (1854) pp. 27–29, 40; Howson (1841) p. 84; Registrum Monasterii de Passelet (1832) pp. 121–122; Document 3/19/4 (n.d.). Dubhghall is listed as one of witnesses of the transaction.Argyll: An Inventory of the Monuments (1992) p. 258 § 119; Campbell (1911) p. 278 n. 1. Other attested witnesses were Murchadh,Argyll: An Inventory of the Monuments (1992) p. 258 § 119; Sellar (1971) p. 27; Campbell (1911) p. 278. and Murchadh's brother, Donn Sléibhe.Sellar (1971) p. 28.

Dubhghall is elsewhere stated to have granted Walter Stewart his lands to be held as a "free barony" for two-thirds of a knight's service in the king's army.McDonald (2004) p. 189 n. 36; McDonald (1997) p. 143; Easson (1986) p. 132; Munro; Munro (1986) p. xxxix; Barrow (1980) pp. 68, 138; Campbell (1911) p. 277 n. 1; Brown, A (1889) p. 189; Fraser (1888a) p. 63; Origines Parochiales Scotiae (1854) p. 29. Additional evidence of the Stewarts' takeover of the Clann Suibhne heartland includes the record of grants of Walter Stewart of several Knapdale churches—those of St Abbán moccu Corbmaic (Keills Chapel), St Michael (Kilmichael of Inverlussa), and St Mary/St Máel Ruba (Kilmory Chapel)—to Kilwinning Abbey.Barker (2017); Argyll: An Inventory of the Monuments (1992) pp. 85 § 45, 150 § 71, 161 § 76, 258 § 119; Paul (1909) p. 131; Bliss (1895) p. 311; Fraser (1888a) p. 63; Fraser (1888b) pp. xxxi § 13, 220–221; Archæological and Historical Collections (1878) pp. 163–168 § 17; Theiner (1864) pp. 248 § 488, 257–258 § 504; Document 3/19/5 (n.d.).

The circumstances surrounding of Dubhghall's contract with Walter Stewart are unclear.Forte; Oram; Pedersen (2005) pp. 255–256; Barrow (1973) p. 373. There are no other records regarding the allotment of Clann Suibhne lands during this period, and it is not known if the Stewarts or their allies had already established themselves in Knapdale.Argyll: An Inventory of the Monuments (1992) p. 258 § 119. The transactions involving Clann Suibhne reveal that the family was progressively deprived of its territories. Whether the charters are evidence of a military invasion is unknown.Forte; Oram; Pedersen (2005) pp. 255–256. The creation of a Stewart lordship in the region may have been undertaken in the context of extending Scottish royal authority into Argyll and the Isles.Forte; Oram; Pedersen (2005) pp. 255–256; Young (1990) p. 15. From the perspective of both the Stewarts and the Scottish Crown, Clann Suibhne seems to have represented a significant threat to regional stability. The removal or destruction of such families appears to represent part of a strategy to not only dislodge unpalatable kindreds (like Clann Suibhne), but forge new partnerships with more loyal kindreds, and extend the power of committed agents of the Scottish Crown (like the Stewarts).

Norwegian campaign

Whilst Alexander II projected Scottish royal power into the south-west Highlands, Alexander III focused his effort upon the Isles.Forte; Oram; Pedersen (2005) p. 256. In 1262, the year after yet another failed attempt by the Scottish Crown to purchase the Isles from Hákon Hákonarson, King of Norway, the thirteenth-century Hákonar saga Hákonarsonar states that Hákon was alerted that his Scottish counterpart sought the subjugation of the Isles,Crawford or Hall (1971) p. 106; Duncan; Brown (1956–1957) p. 212; Anderson (1922) p. 605; Dasent (1894) pp. 339–340 ch. 314; Vigfusson (1887) p. 327 ch. 314; Unger (1871) p. 569 ch. 322; Flateyjarbok (1868) p. 217 ch. 274. and was informed of recent Scottish aggression in the region, including a particularly savage attack upon the inhabitants of Skye.MacInnes (2019) p. 129 n. 52; Cochran-Yu (2015) pp. 46–47; Wærdahl (2011) p. 49; Broun (2007b) p. 4; Barrow (2006) p. 146; Forte; Oram; Pedersen (2005) p. 256; McDonald (2003) pp. 56, 132; McDonald (1997) p. 106; Duffy (1993) p. 109; Cowan (1990) pp. 117–118, 130 n. 70; Reid (1984) pp. 18–19; Crawford or Hall (1971) p. 106; Duncan; Brown (1956–1957) p. 212; Matheson (1950) p. 196; Anderson (1922) p. 605; Dasent (1894) pp. 339–340 ch. 314; Vigfusson (1887) p. 327 ch. 314; Unger (1871) p. 569 ch. 322; Flateyjarbok (1868) p. 217 ch. 274. Thus provoked, Hákon assembled an enormous fleet—described by the Icelandic annals as the largest force to have ever set sail from NorwayMcDonald (1997) p. 107; Storm (1977) p. 135; Anderson (1922) p. 607; Vigfusson (1878) p. 377; Flateyjarbok (1868) p. 534.—to reassert Norwegian sovereignty along the north and west coasts of Scotland.Alexander; Neighbour; Oram (2002) p. 18; McDonald (1997) p. 107. The fact that members of Clann Suibhne were unwilling to subject themselves to Stewart domination is evidenced by the record of Murchadh supporting the Norwegian cause.
