Was contacted by April, who is helping work out the ancestry for Danny, the man who reached out to me but didn't know his paternal ancestry. April's husband is also a DNA match for Danny.
In looking at his GEDMatch number, her husband didn't match me, my dad or my 2nd cousin, so this leads me to believe that we are both related to Danny on different lines.
Danny's connection to me is estimated to be at 4.4 generations to the most recent common ancestor at GEDMatch, we match at chromosome 6.
Hopefully, some of the other matches at chromosome 6 will overlap with Danny and provide some clues as to who the common ancestor might be.
I know that it is possible, as I have read about these cases being solved on various DNA discussion groups. We just need more to test.
