Subtracting those 50 matches and the 3 immediate family from her total shown 4th Cousins or closer match total and she has 2,266 4th cousins. For the record all of Mom's 3rd cousins or closer have been asked if they would consider uploading their results to GEDmatch. Looking at Mom's matches made me curious how the numbers compared to my results as well as those of my daughter, and my sister.
Mom is very fortunate to have many of her closer cousins who have tested. I wish more of the closer cousins would upload to GEDmatch. It certainly would make sorting the matches easier. In the end though it is their choice and more times than not, it is just not a priority for them.
