I have some info on Paul Alder which may be of help. He was born in 1779 in Rockingham Co. VA. His wife's first name was Margaret. This info was obtained from the records of Kay Groom Gibb of Victorville, Calif. Also, refer to the marriages of Gloucester Co., NJ;abstracts of wills; deeds of Wythe Co., VA.; volume 15 Old Northwest General Quarterly; Biography of Jonathan Alder; and Marriages of Montgomery Co., VA. I hope this will help. Sorry I don't have more.
