**Type A 9 traces to Sister to Mixbury number one through Maid of Masham and includes: Cyllene, Start Shoot, his son  Sir Barton, Bold  Forbes, Bull Lea, Tom Rolfe, Fair Play (9-a) and Ack Ack. *A is unique haplotype.
**Type G 9-b,c  traces to Sister to Sloven (1728), dau of Sister to Mixbury number two and includes: Mumtaz Mahal, known as "the Flying Filly," and considered  one of the fastest  two-year-olds of all time; Nasrullah  and his full sister Rivaz (1943);  Royal Charger; Abernant; Mahmoud; Risen Star; and  Shergar. *These "G" variant horses derive from the  same founding mare as the three  tested in Fam 12, whose pedigrees were traced back as far  as a 1723 mare by Greyhound who was a daughter of a mare by the  Curwen Bay Barb. Three extremely  significant stallions, and many more  influential horses, descend  from the family 12 founding mare, and thus probably  carry the  "G" haplotype: they are Eclipse (1764), Lexington (1850),  and Commando (1898).  Because questions have  been raised by historians regarding Eclipse's  dam line, and because Lexington's  dam line was considered so ill-documented  by the GSB at the turn of the  20th century that he and  all but a few of his descendants were barred from entry  in the GSBin 1913, additional testing of more horses descending  from  family 12 will be of great interest.
