My son recently had a match come up as close family the match is male and 1814cm.
His only living grandfather is already in our tree at 1857cm. All other grandparents are deceased and have never participated in Ancestry DNA.
When I review the shared matched between my son and the matched male they have matches consistent with my ex-husbands family. However none of my ex husbands brothers (his uncles) have done DNA testing.
My son has no grandchildren.
Is it possible that 1814cm could be the child of one of my ex husbands brothers children or am I looking at the possibility that there is a half sibling to my son?
