Brice Blair & Susanna _____
James Blair & Amelia Brayfield Hagerman

Conventional Research
According to Charlotte Stewart's book, "Blair Society for Genealogical Research Members� Lineages (1983 - 2003), with Biographies of Their Earliest Ancestors", James Blair (and Amelia Brayfield Hagerman) may be the son of Brice Blair and Susanna _____ who died in Bean�s Cove, PA in 1785. Positive proof has not been found for this relationship, but research is on-going to determine if this James is the same James Blair named in the will of Brice Blair in 1785. New evidence, since the book was published, further supports the belief that James is the son of Brice.

DNA Testing
We have two participants (#4990 and #131869) who descends from Brice Blair and Susanna _____ through son Brice II and two participant (#32588 and #42399) who descends from James Blair and Amelia Brayfield Hagerman. Participants #32588 and #42399 match 25 for 25 with each other and #131869 and 24 for 25 with #4990. 

The actual marker values for each participant are shown in the table below.
