AKA South's Dam
Family 13 descends to the present through two daughters of Sir Ralph Milbanke's black Makeless mare: the SOREHEELS MARE (South's dam) and Gipsy, by King William's No-tongued Barb, although the descendants of Gipsy (branch 13-d) are much less numerous. The SOREHEELS MARE has had an entry in GSB since the edition of 1791; her dam has been given consistently in all editions as (the dam of Hartley's Blind Horse) by Makeless, out of Christopher Darcy's Royal Mare. Her breeder was identified as Capt. Hartley starting with the 1808 edition. In various eighteenth century pedigrees her dam was also referred to as a Darcy Royal Mare and, in one pedigree, as Ld Darcy's Royall mare.https://www.bloodlines.net/TB/Families/Family13.htm
