My grandmother was Pearl Sell Schawyer, who was born in Van Buren County, Iowa. Her mother, Mary Ann Holland, was married to David Sell in Illinois in 1870. His parents were Catherine Bodenhammer and Ruben Sell. After the death of David, in 1878, Catherine and her son and his family, Barabus and Polly Sell, moved to Van Buren County, Ohio. My grandmother was born in 1887, 9 years after David died, but her two older brothers were Davis'd sons. Any help?
