My maternal grandfather was Benjamin Oscar Duggan, Jr of Chattanooga, TN, who was the son of B.O. Duggan Sr and Barbara Graves Duggan. His grandfather was the Dr. Benjamin Frederick Duggan of your email. B.O. Duggan Sr was the Commissioner of Education in TN during the 1930s and B.O.Duggan Jr was an attorney in Chattanooga from 1934 until he died in 2001.
Are you looking for descendants or ancestors of B.F. Duggan?
