To answer the original question about using blood characteristics for tracing ancestry. Dr. Albert Casey tested thousands of Irish and other Europeans for 15 to 20 characteristics for blood (Rh included). He published a series of large source material books (16 volumes) on his Munster, Ireland ancestry but several volumes have his research on usage of blood characteristics to determine relationships between donors. Unfortunately, there is some Eugenics included as well (skull dimensions). If you want to know how blood characteristics can be used for tracing ancestry, this is a pretty interesting study of blood characteristics done in the 1950s which have a genetic genealogy component. These volumes are located in National Library of Ireland as well as the Hunstville, AL public library (and many other libraries).
These volumes have a lot of genealogical source material for County Cork and Kerry and these blood studies are extremely unique research for pre genetic genealogy research (they are pretty heavy reads and would help to have a good understanding of these blood characteristics):
