All on both sides have tested with ftdna. In addition one sister tested on Ancestry and that is the only result on Gedmatch - none of the ftdna are.
The sister on Gedmatch has this on chromosome 23 compared to me though she isn't on my list of matches - 44916961-51207222 (8.8919 cM), 51361035-68051531 (4.5881 cM), New Root. No X compared to my brother.
On ftdna:
On my results - 3 of the 4 sisters have X.
Sister 1 - my 3rd match overall and on chromo browser total 15 segments and though she is an X match nothing on 23.
Sister 2 - my 4th match overall has total 22 segments but none on chromo 23 though she is an X match.
Sister 3 (the one on Ancestry on Gedmatch) - lower down my list of matches and has X match and has total 15 segments spread over chromo 23 and 12.
Sister 4 - not an X match to me and not on my list of matches.
Person 5 - likely daughter of one/niece to others is an X match to me with total 15 segments over chromo 23 and 12. She is on same chromos as Sister 3 but Person 5 has the sister's maiden name - maybe a 5th sister?
On ftdna:
On my brother's results - nothing on chromo 23 / X for chromo browser for anyone.
Sister 1 - his 4th general match and the only one who has X match on the list but on chromo browser nothing on chromo 23. Total 17 segments.
Sister 2 - his #7 match and total 15 segs.
Sister 3 - low match and total 13 segs.
Sister 4 - his #2 match after me and total 17 segs.
Person 5 - low match and total 15 segs.
I hope this isn't too confusing. It would be better if all were on Gedmatch.
