I may have some information about Joseph Lawrence Aaron. His father, William Riley Aaron, was my great-grandfather. I know who some of their descendants are. I also have a photo of William Riley Aaron with his son Joseph. Please contact me, and I'll see if I can help. I have NOT been able to find out where William's father, Benjamin, came from. Have seen the name Dock in something I received many years ago. Also,I met Ethel Aaron Brown many years ago. My address is firstname.lastname@example.org.
