According to my information, Agnes Jane Pitcher married Silas S. Bowen on 4 Dec 1852 in Holt Co. He was born 1824-1828 in VA according to the 1860 & 1870 Holt Co. Census. Their children were Balis A., Hiram, Nancy J. and Eliza, who was born 1869-1870 in MO according to the 1870 Holt Co. census. Eliza is listed as a stepdaughter of Michael Eastman.
Agnes married George Michael Eastman on 15 Feb 1874 in Holt Co., MO. He was born 12 Dec 1830 in PA and died on 10 Feb 1904 in CO. Prior to marrying Agnes, George Michael Eastman was married to her sister, Henrietta Pitcher (his 2nd wife). He was also married 1st to Nancy J. Highnight and 4th to Nancy Wade Saygar.
I am descended from Agnes' sister Angeline who married Levi B. Wheeler. Agnes' parents were Hiram Pitcher and Eliza Harrington. I have additional information and sources I would be happy to share if you want to contact me directly. My e-mail is firstname.lastname@example.org
