The CARROLL and GELLERT families

I am confident that there is unlikely to be any shared DNA in the ancestors of the CARROLLs and the GELLERTs, due to the fact that both branches were relatively recent US immigrants, from different places, so that it is unlikely that these families had unknown intermarriages in the genealogical time period.  Proceeding from that assumption, therefore, segments can be clearly assigned to one side of the family or the other.

My mother Mary's DNA as well as that of all my full siblings has been tested.  Joe Carroll, her brother, has also been tested, as had Jim Gillert*, their cousin.  Mary and Joe's DNA is from either their mother's [the GELLERT's) or their father's [the CARROLL's] side of the family (their sister Pat died in 2002 and her DNA is not available).  Segments which match Jim and also Mary or Joe are GELLERT segments and can be excluded from the CARROLL family.

My genealogical DNA plan

Having obtained DNA tests for many members* of my family and done nothing much with it, I have decided to create and put into action a systematic plan to identify which bits of DNA can be identified with which ancestor. 

The first step in my plan is to identify which DNA segments can be associated with my mother [the CARROLL and the GELLERT families] and which DNA can be identified with my father [the McCORMICK and the TAYLOR families].  

The point of the identification is to identify segments that will allow me to find and confirm descendants from common ancestors, possibly breaking through genealogical "brick walls" through the use of DNA.

It is my hope that keeping track of my goals and my progress will help me keep this project on track.

* Autosomal DNA tests for my mother, Mary; her brother, Joe; their maternal cousin, Jim Gillert; and all four of my mother's children Joni, myself (Jere), John, and Sara: as well as well as Y-DNA tests for the males. Autosomal DNA is usually abbreviated as "atDNA", but for my purposes here I will shorten it to DNA and specify otherwise if I am referring to any other type of DNA.
