John: I have a John James Medlin (1851-1888) who married Ellen Hanum.Their children were Maarguritta Selena, James, Matilda, John William (1880-1946) who married Beulah Valiton (1893-1978), Isabell, and Idabell.
John James left Highland, WI and moved to Colorado.He changed his name from Middlen to Medlin after he moved there.
John James was a brother to my grandfather Daniel Middlen.
John James and Beulah had 3 children:James Rodger, John, and Dell.
Let me know if this fits in with your family.If so, you and I probably are cousins, and great grandchildren of James and Matilda.
