Robert KEEVER was my 5th G-Grandfather. He was born 11/7/1787.He was married to Anna R. ROTHROCK. She was the daughter of George ROTHROCK and Elizabeth MYERS. Anna was born 1/14/1793. I have slightly different death dates then you mentioned. For Robert I have 5/28/1867 (same date, 2 yrs earlier) and Anna 2/18/1864 ( 10 days difference).
My 4th G-Grandfather was George KEEVER. George was born 5/6/1821 and died 8/24/1894. He was married to Susan WRIGHT who was born about 1815 and died 9/25/1897. Their oldest daughter, Sarah Catharine KEEVER, was my 3rd G-Grandmother. She was married to James Otis WEAVER in White County, IN. James and Sarah's oldest daughther, Susan WEAVER, was my GG Grandmother. She was maried to George GARLAND.
George KEEVER also had brothers named Robert and John. Did their sister Margaret Keever SMOKER live in Pennsylvania or Indiana ? It appears that some of the Keevers and Rothrocks came to Indiana in the 1850's from Mifflin County, PA.
