I've found some add'l info on Wm Arthur and Flora Amanda Cobb. Your 11/19/99 msg stated Flora's b. as 1 Sept 1857 in East Branch, PA. My atlas doesn't show E Branch. Is it in Warren County? Anyway, a page from some genealogical/history book or magazine that was sent to tme from the Erie County Historical Society shows Flora Amanda Cobb as b. 1 July 1860 and d. 8 May 1917 in Viana, Maine. Her parents were Edmond I and Amanda Logan Cobb. Flora and Arthur had two children, born in Eldred, McKean County, PA: Elroy, b. 29 Sept 1882, d. 22 Oct 1902 when he slipped while crossing a fence and shot himself; and Ethel Gertrude [Effie], b. 7 Nov 1884 [in the next pp it shows Effie b. 9 Oct 1884]. Effie married Marvin R Monroe 11 July 1903 and had six children: Emily Esther b. 5 June 1904; Bernice Edith b. 22 March 1907; Anna Belle b. 25 June 1908; Florence May b. 29 April 1911; jessie Marie b. 11 May 1913, d. 28 June 1914; and Henry Arthur b. 1914. Was Henry your father? There's also some info on Flora's brother, Clinton Myron Cobb, his wife, Sadie Kealy, and their four children, but since my inquiry was about the Olmsteads, they didn't pursue the Cobb line in what they sent me. You probably have all this stuff on the Monroes and the Cobbs, but what piqued my interest was the disparity in the birth dates for Flora. How confident are you in the 9/1/1857 date?

if you want to reply directly, and if you want to give me your e-mail address, I could send you my Olmstead family sheet, as I have it so far, and we could exchange info as we discover new stuff.
