In the event the Terry region-paired myself every-where you to definitely she part-suits their mommy which this lady mommy part-fits me personally, we

People I am aware courtesy genealogy and family history delivered me personally brand new screenshot more than (taken before FTDNA biracial Dating Seite kostenlos added the newest X-chromosome), made while you are logged into their mother’s FTDNA package.
