Ancestral Family Tree DNA Testing / Re: X Match interpretation

Ruskie, any DNA you have including any on the X chromosome has to have come from one of your parents. If your father does not have an X Chr match with LB he can't have passed that segment on to you.
Having stated the obvious, there is a problem with X matches in that they aren't terribly reliable. Anything less than 20cM's is likely to be false.
There has been a study in which several trios of daughter/mother/father matches were examined and it was found in all cases that an X match under 20cM's with the daughter did not have a corresponding match with either parent.
