I am searching for information on a William McCormick of South Shenango Township, Crawford County, PA. He was living there in 1830, 1840 and 1850. In 1850 he was age 77 and born in Ireland. He was living with a Sarah age 38 (a daughter?) Joseph 28 and Rosetta, 29 (son & wife). I believe he was the same William McCormick buried at the State Line Cemetery who died April 2, 1857. Buried with him were Joseph W. McCormick, Rosetta. The William in the cemetery had a wife named Mary. I descend from John M. McCormick (wife Jane Magee), and I suspect William was John's father. John's son was William H. McCormick who is also buried at State Line. I know John's father was born in Ireland. John and Jane had the following children: William (m. Nancy WADE), Andrew (m. Ellen DAVIS), Sarah (m.John WHITE) and Mary Jane (m. a KUDER). Is anyone else researching this family, or have knowledge of them? Any help is greatly appreciated. Linnea
