I have no information on this unknown huisband I am searching for. In fact, the only things I know are:

He married Marie AFTER the 1920 census.
They divorced BEFORE the 1930 census.
Marie was living in D.C. in 1930 and working as a secretary for a congressman. She remarried later to B. Frank Murphy and later to Dr. John Orem, surviving both of them. She and Mr. Clerk had no children.
