I am searching for any living relatives of William Joseph Bonner jr. (brother to John Carl Bonner). They were born in 1922 and 1924 respectively. William Joseph Bonner jr. died in 1988 in West Hills, LA, CA. I would like to find out who his wife and (if applicable) children are. Their father was William Joseph Bonner Sr. who was married to F. Sumann.

William and John had an aunt named K. Sullivan who birthed a Peggy Sullivan. I do not know if the aunt was a paternal or maternal aunt.

Both William and John were born in Chicago Illinois.

Any leads would be appreciated.
