I saw your message about Martin Earhart & Mary Studebaker.I volunteer every Wednesday at the Studebaker Family National Assoc. in Tipp City, Ohio.I also have SFNA Vol.I. They are listed on P.169.Says they were married 8 Dec 1825.Martin was born 5 Feb 1799 in Va. s/o George Earhart and died 1 Oct 1852 and is buried in Earhart Cem. Greenville Twp. Darke Co.Ohio.Lists children: George b. 1825, Mahala b. 1829, Martin b. 1831, Mary b. 1835, Elizabeth 1838, Abraham b. 26 Jul 1840 d. 15 Jan 1849, William b. 1843 and Maria b. 1847. After Martin's death, Mary married Zacharia Brandon and lived in Greeenville Twp. Darke Co.Ohio. I live about 60 miles from Greenville but have never heard of Earhart Cem.Probably on their property.I go to Greenville quite often since all of my husband's family are from Darke Co. Ohio area.Hope this helps.
