I am not sure if you will get this as your post is quite old. I have just discovered that I am a direct descendant of Elizabeth Waldenmeyer. I am headed back to New York for genealogy work on her husband, John Garrett and his family line.
I am interested to know if you have found any additional information on John A, Thomas or the first Garrett to arrive in American Colonies.
I am also interested in finding more about the Waldenmeyer line. Do you have Elizabeth's parent's name and vitals?
