It is FULLY sourced and includes several corrections to previous, generations-old Terhune Family Trees.
You asked: "If Geertje was listed as the wife of a ribbon weaver and there were not very many people in the United States at that time, and probably not a lot of ribbon weavers, does it not stand to reason that her maiden name was Dircks? and if not, why not?"
The answer is:"patronymics." Before the Brits took over New York, most of the Dutch settlers DID NOT have or use surnames of any kind.Our immigrant was:"Albert Albertszen" (various spellings) which meant "Albert, son of Albert (no surname)".Our immigrant's children would also have "Albertse" as a 2nd name, because the GIVEN name of their father was "Albert"
"Geertje Dircks" meant "Geertje, daughter of Dirck (no surname)". OR, if she were the widow of a man named Dirck, (just to keep life challenging) she might ALSO have been called "Geertje Dircks".In short, surnames did NOT pass down in those early Dutch families.
You also made reference to search difficulties.Practice makes perfect!Because our Terhune surname took on sooooo many different spellings through the years...I often get much better results by searching for just: "Terh". (without the quotes).Or: "Vanv" for Van Voorhees, Voorhies, etc.for the same reason.
