With the growing number of in-laws in my database, I ran into more and more instances where these in-laws were related to each other. For some families, I decided it would be easier to do a bare-bones tree of the ENTIRE family to highlight relations. For many of these families, I discovered links I didn't even know existed.
This is what I would consider VERY PRELIMINARY research. While I tried to make sure the information below is correct, I guarantee that it is not. As always, do your own research (always, always, always).
