Frankly I'm not sure but I think you may be a cousin.Was (is) your mother's name Phyllis?If so, you probably know everything I do about the family "secret" because I get my information from Bobby either directly or through my brother Ed who communicates with Bobby more than I.
I just ran into this old post because I was looking up someone in Uniontown who works on car parts and since I was on a Uniontown website decided to plug in the family name that lead me to your post.I seem to remember two girls, Phyllis and Uncle Glenn so I'd be surprised if you are not one of the two girls.
Frankly I've lost track of the Renninger side of my family, except for my brother, of course and really haven't communicated much more with my mother's side of the family either for many years.No real reason, just sometimes life gets in the way.
If this post reaches you and you want to explore some let me know. I'm online a lot and would like to know if we are indeed related...
I guess the other thing that makes me believe we have a family in common is my Grandfather's name was Irving and that is also my middle name!Ha!:-)
