My Longcor's didn't stay in Michigan after Oscar died. He had one natural son, Andrew Jackson Longcor, who had 3 daughters, and on adopted son, Francis Howard Longcor b 1867. Francis married Effie Hawkins in 1892 in Dodge City, KS. I don't know if they had children or where they went after that, except Effie died in Colorado after 1940. I know that doesn't sound like much help.
