Hello! I'm new to this list but have been working on my HARRISON surname for quite a while now. My mother's maiden name was HARRISON, and I am seeking her gr-grandfather, WILLIAM (Henry?) HARRISON, who, according to an article on his son, GEORGE HARRISON (1829-1905) in "Memoirs of Allegheny County", was of Scotch descent, the son of JOHN HARRISON (possibly a coal miner in McKeesport after 1824), but was reared in PA. Then, according to an article on him written in another of the histories of Allegheny County (can't put my finger on it at the moment) it said "The family of Harrison has been represented in Western PA for many years, its original seat being in McKeesport and Port Perry. William Henry Harrison, grandfather of Richey C. Harrison (my grandfather), of Turtle Creek, was a native of Allegheny Co. PA. He was one of the pioneers of Port Perry, where he owned a saw mill on Crooked Run, run by water power, a motive that has almost altogether been supplanted by steam. He married" (Elizabeth ????) and they had, I believe, nine children, among whom was William E., George, Ann, and Walter B. Harrison. My problem - especially since he has the same name as the President of the U.S. - is that I keep getting material on the President when I put in queries about gr-gr-grandpa! Any suggestions? If his first child was born in about 1819, he would have been born sometime before 1800, and possibly as early as 1790. His last child was born in 1834. Elizabeth lived with members of the family in the 1850, 1860 and 1870 census reports. (Listed as deaf.) Well, any suggestions that you might have would be appreciated.
