Sometimes naming patterns can suggest a relationship, and you can theorize how someone is connected into your family. But sometimes those assumptions are wrong.
More than two years ago,
I wrote about Ukraine's Books of Sorrow, in which various districts of Ukraine attempted to list those killed during World War II. (If you didn't read that post and you have relatives from what is now Ukraine, it's worth
checking out the post.) In that post, I mentioned that there was a Smil-Mozesh Ruttner (born August 14, 1928) from the town of Tyachiv who was listed as having been killed in the war. Since my great-great grandfather Shmuel Moshe Rutner had died in nearby Kolodne in the previous month, I theorized that this Smil-Mozesh was the child of one of my great grandmother's brothers--possibly one who I hadn't yet discovered.
