I am also on the hunt for him as well. My Gr-grama is Minnie Hubbard now Minnie Rose. We were told that she was giving to the Roberts family when she was young because her parents could not care for her. She remembers a sister she thinks. She remebers her father coming to see her as she got older. William is on my family tree, I think he is the father of William Hubbard Jr whose is Minnies bio father. If you have any information to share I would glady appreciate it. My email is firstname.lastname@example.org
Please contact me asap. Thank you.
