Burton's Barb Mare, is listed in the General Stud Book, with the subtitle "Mr Burton's Natural Barb Mare." In old pedigrees she is referred to as "a Burton Barb Mare," which, after the style of the day, probably indicates she was a daughter of Mr. Burton's Barb stallion. However, it may be the GSB has confused information and that there was no Mr. Burton, and rather the mare was based at Constable Burton Hall, the family seat of the famous horse breeding Wyvill family, and she is owned by William Wyvill, 4th Bt. (1645-1684), who owned the mare [Old] Clubfoot

She has 4 recorded foals:- a filly by Dicky Pierson, through which Family 2 descends to today;

a filly by Dodsworth, the descendants of which include a number of 19th century classic winners; a son St Martin; and a mare by a son of Curwen's Bay Barb which is 4th dam of unsuccessful stallion Dotterel

All we know of Mr. Burton, if he existed, is that his first name may have been Dick or Richard, and he may have been connected with the Royal Stud at Hampton Court.
