I too am searching this family, it is his wife's side,
of Augusta Lorenz. Have you received an obit for Clarence?
Augusta's line appears on Ancestry but under a different
spelling of her father's first name so I had a problem
finding them. I did find the date of death of Augusta's
mother who I have been tracing as she is wht wife of my
great Uncle Detlef who is a brother to my grandfather
Hinrich Lorenz. If you get an obit let me know.
