I am working on a Weegar family tree. Henry John Weegar (b. 12/29/1790) is my g.g.g grandfather. He married Elizabeth M. Weaver (b. 3/2/1796) from Williamsburg, Ontario. I have Peter Weaver (b. 1756) as Elizabeth's father.
I don't have much information on Elizabeth's family but have quiet a bit for Henry John Weegar (as far back as 1650 in Germany). I do also have Marcellus/Marcelis family members but none by the name of John.
Let me know if you would like more information.
