Although my surname is spelled Giammo, it was originally Giambo'. I have my own and another Giambo's Y-DNA tests and we are perplexed that they do not match up at all. We need at least one other male Giambo to volunteer to have a Y-DNA test to begin to figure out what is going on.
If any such male Giambo is willing to have their DNA tested, please let me know. Some financial help can be made available. You can reach me at email@example.com
