Adding to what everyone else has posted, sometimes it just takes years to find people or for them to find you. The late Stephanie WIENER and I met via Family Finder and she told me my great-grandfather, Isak GOLDMAN, had 4 sisters who had emigrated to the USA. This was a complete surprise since no one in my GOLDMAN descendants knew anything about this.
I won't delve into other finds and other still unsolved mysteries, but again -- sometimes you have to just live long enough to either find the answers yourself or have someone else contact you.
In the meantime, I do what I can to help others, especially if they had family in the towns for which I created 6 KehilaLinks sites. Then, I ask them for stories and photos of their families to make those available to other researchers.
If you haven't considered creating a KehilaLinks site for one that doesn't yet exist, I recommend that action.
Yes, we are weird!
