Hartman's of NE Ohio

Searching for Hartman's who resided mainly in Portage County (Windham and Garrettsville county) and Akron (Summit county) and Youngstown(Mahoning county). The Hartman's may have migrated from Pennsylvania. Looking for info on George Hartman born June 18, 1892 died 1945. Was married twice and divorced in Akron, then moved to Cleveland. He has a sister Sylvia married to a Higgins. Parents of George were Peter John Hartman (or John P), his wife Sara (Hushour) or for some reason, was also shown as Luna P Tyler, He was also married to Martha Lewis. Peter was born 1/10/1875 and died May 20, 1925. I do not know who his parents were. Peter was born in Indiana but later moved to Ohio. I would be most appreciative for any info and am willing to share info.
