Thank you Fox and Catsy for looking all of that up! BTW, I think it's kind of funny that we're a fox, cat, and bird. I hope nobody's hungry because I would be at the bottom of that food chain!
The people finder idea helped a lot and some other googling led me to a list of Frank Sr. and Louise's heirs, so that gives me a good idea of who the kids were.
I mainly want to know who they are so that if I find anything that indicates other kids lived with them, I can narrow it down. I also figure if I can find his biological kids in yearbooks or something, I might be able to find the Sodders among other kids there, most likely with different names.
It looks like Edward and Frank Jr. still live there. I know someone needs to question them about they know know of their cousins, but I don't want to do it myself just yet. I know they're probably nice guys, and even if their family was involved, they likely were told the same story as the Sodder kids, but I don't want to take any chances just yet. Maybe by some miracle I'll come across some evidence that proves they were there, and if I do I'll take it to law enforcement and let them ask the questions. After all, a lot of people have been afraid to talk for many years, and we still don't know if the family has mafia connections. I'd rather talk to people who knew the family (like schoolmates) before I talk to the family themselves. If I find nothing useful, I'll probably go back on a later trip and talk directly to family members if I can. Maybe I'm paranoid, but I am a young lady who will be traveling there alone.
