I seem to have hit a dead end on my 5x great-grandfather, Robert H. Harrison, born about 1804 in Northern Ireland (possibly County Armagh) and died before 1900, probably in Cuyahoga Falls, Summit County, Ohio. I do not know when he came to America, but it was sometime before 1835, when his daughter Eliza Jane was born. I do not know much more than that. He had a wife, Anna (unknown last name), born 1803 in Ireland, although I dont know if she and Robert were married before or after they came to the states. In 1870 he is living in Cuyahoga Falls, Summit County, Ohio, age 66, born in Ireland. I cant seem to find anything on him before or after 1870, but I do know he lived in the Cuyahoga Falls area his whole life. Does he ring any bells, and if not can anybody point me in the right direction of where to look?
