I have just come across this site on a Yahoo search for "Warthan's". I do have fairly complete family tree going back to John Warthan.Sylvester J. would be my great-uncle.There are a number of Warthan's who meet yearly for a family meeting to conduct business of the family cemetary.
If you have anything compatiable with the Family Tree Maker I could E-Mail a copy to the family tree I have. An older verison is also on a CD from Family Tree Maker. I would be interested in filling people that I have no record of.
