The "Biographical Annals of Franklin County, Pennsylvania" lists a Mary Seibert "maried John Denig, and they had issue: Ann (who married first) Mr. Foster, had one son, John, (and second) WilliamG. Mitchell, Clerk of the courts, 1860-1866; Kate, who married charles Williams; and Sophronia who married John Bechtel." Mary Seibert was b. abt. 1807 and d. 26 Sep 1827.She was the d/o Philip Seibert and Ann Miller. The only information that I have on the Denig family not listed in the Biographical Annals of Franklin Co. is a listing for graves of John and Mary somewhere in Franklin Co., PA.The list did not have dates and the key to find the cemetery was not on the page.Can anyone help with this family?
