I am totally loving everything you said about WikiTree being so exciting and so much fun.
My problem (at least what I think is my problem) is that I know very little about my ancestors.
My father's family name was Gordon, but that might have been something made up by whoever processed his father through Ellis Island, because his father came from Russia and Gordon doesn't sound very Russian to me. On top of that, I don't even know what my grandfather's first name was. He abandoned the family when my father was very young and nobody ever mentioned his name after that. I have found what I believe is the immigration record for my paternal grandmother, who came alone from Russia when she was 13-15 years old. She's listed on the ship manifest as Sore Brzeynik (again, probably someone else's interpretation). She (and a few relatives I know about) used the name Bresnick in this country.
My mother's family name was Lichtman and I have made the most progress there. I knew my maternal great-grandmother when I was young. Her name was Deitel and I have managed to find her LNAB and her husband. They came from Hungary with their 4 children, I also know all about her children and their families - actually, I know quite a bit about the sideways family tree - it's just the backward part that seems to grow out of thin air!
