During the research into my own ancestry, I ran across a few other Zalewski lines in the Milwaukee, Wisconsin area. As one does in genealogy research, I wondered if they were related to me. It turns out that at least one of those lines was related to mine, but the others have not yet been connected. Recently, I spent some time digging into those other lines a little bit and they are now somewhat better organized.
This also helped me start the Zalewski Name Study page over at WikiTree which will hopefully help Zalewski families connect to each other either through paper genealogy or DNA.
