Well, you have a cousin and her mother (plus other family members) that have thankfully done a ton of work on your very line! Her name is Rebecca Hitzman. I believe most, if not all, of her work is accurate. My line, James Williamson's brother, John F., is also accurate, I believe. Neither of us has really been able to (with proof) to get back farther than Joseph Willey which would be (off the top of my head) 3 generations back from John F and James Williamson.
I totally agree with you! Their naming conventions back then make it really really difficult to follow!
I have put aside the (male) side of my various lines for now. I needed a break (e.g., Willey line confusing and difficult to follow...and many records from the around the time I'm searching have been destroyed). Anyway, I'm trying to follow various families from the female sides of my lines. I've discovered they are just about as difficult. I am having a heck of a time trying to find family for John F.'s wife Millie/Milly Margret Morrison. Ugh. It's never ending.
My suggestion to you: Definitely follow Rebecca Hitzman! The specific tree name is something like "Adam/Lawrence..."
Stay in touch! And much luck to you!!
