Hi, I just stumbled across this post, and you are talking about my Grandma's family. This family did have 12 kids, which are my mom's aunts and uncles. Most of the names are correct except for Rosa, which was simply Rose, nobody ever called her Rosa or anything. Also, the one that is not correct is my Grandma, her name was Sophie, not Sylvia. The youngest one is Elizabeth, which is my great Aunt whom I've known since I've been born and grown up closest to. Anyone who wants to ask me anything I'm open to questions. My great-grandparents are Mary and Frank! :)
Also, yes I grew up and am from Kenosha.
