Colonel Pepper's Diamond Mare appears at the head of Family 104. The Turf Register suggests her sire was the North Country Diamond (ch c 1726 Jew Trump), however, her grandson Stump was foaled in 1724 so Mr. Cheny was more likely correct in recording her sire as Darcy's Diamond (c 1680c Fairfax Morocco Barb).

According to the 5th edition of Volume 1 of the General Stud Book, Stump's dam was the Duke of Leedes's mare, by the Holderness Turk. However, sufficient alternate evidence exists, including that from previous editions of the GSB, to conclude that Stump's dam was instead the Snake Mare.

Mr. Humberston's Stump is probably the earliest known runner produced by this family. Bred by Mr. White he first ran under the name of Ladies' Toy. He won Royal Plates at Nottingham, York and Lincoln defeating such horses as Sir Marmaduke Wyvill's Scarborough Colt (bl c 1724 Tifter) and Mr. Coke's Hobgoblin (br c 1724 Aleppo). Stump has the distinction of winning the last Royal Plate that was run over Clifton and Rawcliffe Ings.

The Blacklegs Mare was bred by James Waldegrave (1685-1741), 1st Earl Waldegrave, and owned by the 2nd Earl, also James Waldegrave (1715-1763). She later entered the stud of Charles Colyear (1700-1785), 2nd Earl of Portmore. There she bred the good runners Captain and General, the former a good stallion as well. In 1764 her daughter Cassandra was exported in foal to America and produced Stella for John Baylor (1705-1772) of "Newmarket" in Caroline County, Virginia. In turn Stella produced the stallion Harris's Eclipse who made a substantial contribution to early Virginia pedigrees.

"Mr. Humberston's Stump, Son of Manica, Son of the Darley Arabian. The Dam of the Humberston Stump was got by Snake, his Grand-Dam by Diamond, Son of the Helmsley Turk" [Cheny:1743].

"Blacklegs Mare, Bred by Lord Waldegrave, in 1741, got by the Devonshire Blacklegs, her dam, the Duke of Leeds's Mare,* by the Holderness Turk - Snake - Diamond. * This mare was the dam in 1724 of Mr. Humberton's b. h. Stump, by Manica" [GSB1:34].

"THE Horse called STUMP ... was got by Mannaca, a Son of Mr Darlow's Arabian, the Sire of Childers; his Dam was got by Snake, and out of a Diamond Mare of Colonel Pepper's" [York Courant, March 13. 1739. Numb. 700].

In the pedigree given for the "BLACKLEGS MARE, Her dam, the Duke of Leeds's Stump Mare, by the Holderness Turk - her grand dam by Snake" [Intro:6]. Stump is not mentioned in conjunction with the Blacklegs Mare, although he has his own entry in Part II, which says: Stump, (Mr. Humberston's), 1724, Manica - Snake - Diamond" [Intro:188].

In the pedigree of the BLACKLEGS Mare the pedigree for Stump is given as "Manica - Snake - Diamond" [GSB:1797].

BLACKLEGS Mare's pedigree now reads "got by the Devonshire Blacklegs, her dam, the Duke of Leeds's mare (dam of Humberston's Stump) by the Holderness Turk - Snake," the pedigree of Stump is given as "Mr Humberston's, foaled in 1724, got by Manica - Snake - Diamond" [GSB:1803].

"The STUMP MARE (grandam of Captain) was bred by the Duke of Leeds, and got by the Earl of Holderness's Turk, out of a daughter of Mr. Lister's Snake" [Pick1:179].

In the pedigree for Mr Swymmer's Captain is given as "by Cartouch, out of a daughter of Devonshire Blacklegs, which came from the dam of a bay Horse called Humberstone's Stump" [Pond:1756 & 1757].

When Mr. Humberston's Lady's (or Ladies') Toy first appeared on the turf the pedigree given for him suggests that he was later the horse called Stump (same age & coat color, although the pedigree drops a generation): "bred by Mr White, out of a Diamond Mare & got by Manaca" [Cheny:1729]. The Turf Register also identifies Ladies' Toy as Stump.
