I have a William McKee born about 1847 (no definitive DOB found yet) - Married Margaret Caroline Dillon in 1876, had Thomas Silas McKee September 1876. Margaret dies end of 1876. Thomas listed with Aunt (Elizabeth Ingram) and Grandfather on 1880 census. No listing of William on 1880 or any future census lists.
Thomas moves to Grant county Indiana sometime between 1880 and 1898. Marries Pearl May Kingen in 1898 in Grant County. He and family is there until at least 1930.
Thomas and Pearl possibly died in Dallas TX in late 1960's - Still researching.
