Following the death of her father in 1451, Ottilie claimed his part of the County of Diez as her inheritance.[4][note 6] This led to a conflict with her paternal uncle Count John IV of Nassau-Siegen, who had succeeded his brother in all his possessions[1][5][6][7][8][9] and was granted the County of Diez as a fief by ArchbishopJames I [de] of Trier on 4 November 1451.[10] The conflict was complicated further due to the fact that another part of the County of Diez belonged to Ottilie's father-in-law Philip the Elder of Katzenelnbogen.[11]
In 1481 Ottilie's first cousin Count John V of Nassau-Siegen fully succeeded in enforcing the still unfinished settlement of Ottilie's claims to the County of Diez.[11] In 1485 Ottilie's second husband, Oswald I of Tierstein, attempted to murder John V of Nassau-Siegen because of his dissatisfaction with the marriage grant and the settlement of the inheritance. The Rentmeister [de] of Siegen, Heinrich Weiß, was able to prevent the attempt.[12] The settlement was finally confirmed in 1510.[11]
^In many sources she is called Ottilie 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.
^Schutte (1979), p. 41, Dek (1970), p. 67 and Vorsterman van Oyen (1882), p. 92 all state born in April 1437. Since her mother died on 18 April 1437, Ottilie must have been born before or no later than on 18 April 1437.
^Since her mother died in Breda (in childbirth?), Ottilie was probably born in that city.
^Dek (1970), p. 67 states the year 1450. Vorsterman van Oyen (1882), p. 92 states the year 1449.
^Vorsterman van Oyen (1882), p. 92 states the date of death 30 January 1454.
^The sources do not mention whether Ottilie also claimed her father's part of the County of Vianden.
^Vorsterman van Oyen (1882), p. 92 states the year 1471. Dek (1970), p. 67 does not mention a wedding date.
^In older sources one can also find the spelling Thierstein.
^Dek (1970), p. 67 states the year 1423 without the circa. Vorsterman van Oyen (1882), p. 92 does not mention a date of birth.
^Dek (1970), p. 67 states the year c. 1488. Vorsterman van Oyen (1882), p. 92 states the year c. 1486.
^Dek (1970), p. 67 mentions only the year of death. Schutte (1979), p. 41 states died July (?) 1495. The year 1495 is probably an error because her first cousin of the same name died in that year.
