you have entered the same ancestory as mine. There are several of us on the chat that can trace our ancestory to Jacob Lash (Losch with an umlat on the o). Jacob Lash was born in Germany on 20 Dec 1725. He came to USA in 1740. He married Elizaeth (LNU) and they had 12 children including Phoebe born 1776 and Catherine 1770.
I do not have Zachariah listed as one of Jacob's chlidren. It is possible that Jacob came with some siblings that the Lash descendants are unaware.
Please see under my name in the chat more contacts regarding this lineage. I am not an expert as others have researched the Lash line to the 1600s.
