I have a small black notebook compiled by Wilbur B. Zollman in 1959. It is titled THE ZOLLMAN FAMILY OF VIRGINIA.
Here is some information from it.
William Zollman (1786-1834) married Ann Ripley on 12 Dec 1809 at Fincastle, VA. The father of William is Heinrich William Zollman (1761-1794) who married May Bousman. This William is the first Zollman know to have lived in Virginia. His grandson, Henry, said he came from Pennsylvania, where it is thought he and Mary Bousman were married.
William and Mary settled near Saltpeter Cave, not far from Fincastle, in Botetourt County. Henry said his grandfather was buried at Locust Bottom Church near Gala.
After William died, Mary Bousman Zollman married Peter Dagger but the record at Fincastle, dated March 22, 1794, has Mary's name misspelled "Soloman".
It is said that the Daggers had some children, and that the family finally moved to Inidiana.
