"Philipp I of Katzenelnbogen (1402–1479), also known "Philipp the Elder" was Count of Katzenelnbogen from 1444 to 1479 and was the last male descendant of the Counts of Katzenelnbogen (his two sons died before him). His parents were Johann IV, Count of Katzenelnbogen (younger line) and Anne of Katzenelnbogen (older line), who merged the two lines of the family back together in 1402." - (en.wikipedia.org 01.06.2021)
