I actually an in PA.....with our last name as Willyard.
My tree is public, so if you like, by all means take a look.
I have Johann Peter Williar born in Otterberg in 1714, I do not show where he came over....but he died in Maryland in 1794.
His father was Jakob Viellard.
There a couple of other people on here who I found that have done a TON of research on this tree.
Look for WILLYZACK and J Seaborn(her tree is the Farmerie Family Tree). They both seem have have done alot of work on this and may be able to help you connect some dots.
