On ancestry my son's DNA matches are:-
His oldest half aunt 787cm 11%
Her son so his half 1st cousin 412 6%
The daughter of youngest half uncle so still a half 1st cousin 706cm 10%
I cannot understand why half aunt and her full niece have over 700cms each but half aunts son has only 412cm's
Have you looked at trulines to see who and where people are matching with you though its people putting their own trees on which may or may not be correct.
