I recently received my DNA match from Ancestry,and I share 1,591 centimorgans across 53 segments with one and 1,773 centimorgans across 58 segments with another.

Could these people be half siblings?



DNA Matches of 1,591cM and 1,773cM indicate half siblings as being a possible relationship.

On the strength of those matches the two people could also have one of these relationships to the person tested:

  • Grandparent/Grandchild
  • Aunt/Uncle/Niece/Nephew

but perhaps these can be ruled out on what you know of your family's generations.
