Countess Joanne of Nassau-SiegenIn many sources she is called Joanne of Nassau-Dillenburg. The County of Nassau-Siegen is erroneously called Nassau-Dillenburg in many sources. The county was not named after the small, unimportant city of Dillenburg, which did not even have a church until 1491, but after the, for that time, large city of Siegen, the economic centre of the county and the counts' main residence. See Lück (1981), passim. It is also evident from the numbering of the reigning counts with the given name John. One John without regal number who ruled the County of Nassau-Dillenburg in the period 1303–1328, and eight counts by the name of John who ruled the County of Nassau-Siegen in the period 1362–1638. (1444 – May 1468), , official titles: Gräfin zu Nassau, Vianden und Diez, Frau zu Breda, was a countess from the House of Nassau-Siegen, a cadet branch of the Ottonian Line of the House of Nassau, and through marriage Countess of Waldeck.
