Juan Dengo, also documented as Juan Manuel Dengo (Asturias, Spain, – Heredia, Costa Rica, 11 September 1839), was a Spanish military officer in the service of the Spanish monarchy. His career took place in Central America, within the jurisdiction of the Captaincy General of Guatemala. The Real Academia de la Historia places his birth in Spain. In Costa Rica, he was connected with military service in Cartago and with a family documented in Heredia, two inland towns. He participated in the Cartago municipal council's deliberations on independence in October 1821 and later took part in Cartago's imperialist movement of 1823. His documented career included service as major adjutant, the rank of captain, and appointment as a Knight of the Royal and Military Order of Saint Hermenegild. The staff lists of the Kingdom of Guatemala for 1820–1821 include him as sergeant major of the San Miguel Squadron. Appendix 13: “Planas mayores del reino de Guatemala, 1820–1821”.
Records of Dengo's service and family trace his presence in Costa Rica during the final years of colonial rule. After independence, he appears in proceedings concerning the imperialist movement of 1823 and in an 1827 pardon file.

Spanish origin and Central American career Genealogical research by Yves de La Goublaye de Ménorval, published by the Costa Rican Academy of Genealogical Sciences, identifies Dengo as a native of Asturias, in northern Spain, and his wife, Antonia Alarcón, as a native of Andalusia. Note 407; digital reproduction of the publication.
In conversations with Camilo Rodríguez Chaverri, published in Jorge Manuel Dengo: Memorias del padre del ICE, his descendant Jorge Manuel Dengo Obregón identified Juan Dengo as his great-great-grandfather and stated that “Dengo is a surname of Asturian origin, from Oviedo”. In the same family recollection, he dated Dengo's arrival from Spain to 1802 and described him as an artillery officer. Testimony of Jorge Manuel Dengo; p. 105 of the digital file “Libro de Jorge Manuel Dengo.pdf”, whose passage has no printed page number.
Other immigrants from Asturias were present in colonial Costa Rica. Ramón Villegas Palma mentions Sergeant Major Francisco de la Madriz Linares, born in Asturias around 1689 and settled in Costa Rica, where he married Rita García de Argueta. Another Asturian appears within Dengo's own sphere of activity: the merchant Pedro Antonio Solares y Berros, a resident of Heredia, declared on 2 September 1819 that he was a native of the municipality of Villaviciosa, Asturias, during proceedings conducted by Dengo.National Archives of Costa Rica, statement by Pedro Antonio Solares before Juan Dengo, Heredia, 2 September 1819; FamilySearch digitization, group 108378207, images 65–66.
His Spanish origins and service in Central American units place his career between Spain and Central America. His 1805 commission identifies him as first sergeant of grenadiers in the disbanded Fixed Regiment and assigns him as interim major adjutant to the Yoro Squadron, in present-day Honduras. The service-award account preserves a calculation beginning on 1 March 1798, meaning that his documented military career reaches back to the eighteenth century.
In Costa Rica, his career combined two spheres: service with the Cartago battalion, based in the seat of the provincial government during the colonial period, and family ties in Heredia, a town in the Central Valley. In Cartago he was elected paymaster for 1807 and appears as major adjutant in 1812; in Heredia, the baptisms of his children were recorded from 1807 onward, as was his burial in 1839. This distinction separates his military posting in Cartago from his family's parish life in Heredia.
Military career The Fixed Regiment and the Yoro militia Juan Dengo is documented in the army by 1793. A return of the Fixed Infantry Regiment of Guatemala reproduced by Ana Margarita Gómez identifies him as a 36-year-old married First Sergeant from Asturias. Table 7, continued: Juan Dengo, First Sergeant, age 36, married, from Asturias. UMI 3098593.
The 1805 commission distinguishes his former position as first sergeant of grenadiers of the “disbanded Fixed Regiment” from his new posting as interim major adjutant of the Yoro Squadron. The term “disbanded” describes the corps from which he came in that document and should not be applied to every later unit known as the Fixed Battalion of Guatemala. Indeed, the staff lists for 1820–1821 include a Fixed Battalion of Guatemala among the veteran troops and separately list the Yoro and San Miguel squadrons among the provincial dragoon militia.
Yoro is in present-day Honduras, in territory then belonging to the Captaincy General of Guatemala. The squadron was a dragoon militia unit; the post of major adjutant was distinct from the unit's senior command. The commission was issued by Antonio González Mollinedo y Saravia, Governor and Captain General of Guatemala, who declared that he had “chosen Don Juan Dengo”, identifying him immediately afterward as first sergeant of grenadiers. It was issued in Nueva Guatemala on 1 June 1805. The appointment traces Dengo's transition from grenadier sergeant to a militia adjutancy, expressly designated as interim in the 1805 commission.
Service award and seniority The commission of 1 June 1805 describes him as first sergeant of grenadiers of the disbanded Fixed Regiment and appoints him interim major adjutant of the Yoro Squadron.National Archives of Costa Rica, documents digitized by FamilySearch, image group 107983250, images 609–610, commission for Yoro, 1 June 1805. A later account records a monthly award of six reales from 1 March 1798, when he was proposed for it while a sergeant of the Fixed Battalion, through 31 May 1805, the day before his promotion to interim major adjutant. The claim arose because the certificate had been lost and he had not received the award. Orders dated 7 and 13 May 1808 directed that the payment be processed after the commanders of the corps certified the proposal date.National Archives of Costa Rica, documents digitized by FamilySearch, group 112109336, images 17–19, file concerning the lost certificate and calculation of awards; orders of May 1808. See also https://www.familysearch.org/ark:/61903/3:1:3QHN-LQLM-9JCB and https://www.familysearch.org/ark:/61903/3:1:3QHV-BQLM-9VDB.
The account documents his service as a sergeant in 1798, while the 1793 return establishes that he had already belonged to the Fixed Regiment five years earlier. If the award recognized in 1798 corresponded to fifteen completed years of service, subtraction suggests an enlistment around 1783. Based on the age of 36 recorded in 1793, he would then have been approximately 26 years old. This inference depends on the award category and the method used to calculate seniority; the date on which he was proposed for payment was not necessarily the day on which he completed the qualifying period.
Paymaster duties and service in Cartago On 20 November 1806, Dengo was elected paymaster, with approval granted on 1 December, to serve during 1807.National Archives of Costa Rica, documents digitized by FamilySearch, group 107983250, image 615, election of Paymaster, 20 November 1806, and approval, 1 December 1806. The election record brought together Sergeant Major Juan Manuel de Cañas and major adjutants Juan Dengo and José Prieto; Juan Francisco de Bonilla approved the appointment. The office authorized Dengo to receive the battalion's pay from the Royal Treasury and distribute it among its members. Manuel García Escalante also appears in the records of the subordinate Royal Treasury: his name is recorded in the registration of Dengo's Yoro commission on 20 September 1805.National Archives of Costa Rica, registration of Juan Dengo's Yoro commission in the subordinate Royal Treasury, 20 September 1805; FamilySearch digitization, group 107983250, image 610.

Rank of captain and duties of sergeant major Dengo was granted the rank of captain on 10 August 1815, and the grant was subsequently registered in Guatemala in December 1819.National Archives of Costa Rica, documents digitized by FamilySearch, group 107983250, images 646–648, title of Army Captain granted to Juan Dengo; grant dated 10 August 1815 and later registration. The registered commission reproduces the formula used by Ferdinand VII: “Whereas, in consideration of the merits and services of you, Don Juan Dengo”. The text identifies him as Veteran major adjutant of the Cartago Battalion of Disciplined Militia and grants him the rank of captain of infantry.

A report by Juan Manuel de Cañas, dated 18 May 1820, reviewed his service and recommended that he receive a permanent appointment. The report also records Dengo's request for the rank of lieutenant colonel.National Archives of Costa Rica, documents digitized by FamilySearch, group 112109009, images 13–14, report by Juan Manuel de Cañas concerning Juan Dengo, 18 May 1820.
San Miguel Squadron The table of staff lists for 1820–1821 published by Rodrigo Moreno Gutiérrez places Dengo in the sergeant major column for the San Miguel Squadron, among the provincial dragoon militia. San Miguel is now in El Salvador and was then also part of the Captaincy General of Guatemala. The table distinguishes the San Miguel Squadron from the Yoro Squadron and the Cartago Battalion: each represented a different posting in Dengo's career within a regional military organization. The 1820–1821 list establishes his inclusion on the San Miguel staff but does not by itself specify the date of his transfer from Costa Rica.
Military justice and acting command In 1817, Dengo acted as a Commissioned Judge in a military case. The proceedings identify him as captain of infantry of the Royal Armies, major adjutant, and officer responsible for the duties of sergeant major. He took sworn statements, ordered the seizure of property, and asked Governor Juan de Dios de Ayala y Toledo for authorization and assistance in enforcing the order in the jurisdiction of Villa Hermosa.National Archives of Costa Rica, proceedings in the Marcelo Herrera case, 26 June–8 July 1817; documents digitized by FamilySearch, excerpts preserved as “Declaraciones ante Juan Dengo”.
