The first English thoroughbreds imported into Argentina, around 1853,
were Bonnie Dundee (ch c 1847 Lanercost) and Elcho [ex-Eye the Boys]
(ch c 1847 Harkaway).
Bonnie Dundee, who finished 2nd in the Ham Produce Stakes at Goodwood,
was sired by the Ascot Gold Cup and Cambridgeshire Stakes winner
Lanercost, out of the St Leger winner Blue Bonnet (b f 1839
Touchstone). Imported by Federico Plowes, Bonnie Dundee entered the
stud at cabaña Las Blanqueadas located at Buenos Aires.
Bonnie Dundee Mare, the taproot of this family, out of a
non-thoroughbred ("criolla") mare, was bred several times to Elcho. Elcho, sired by Harkaway, twice a Goodwood Cup winner, was a
half-brother to the useful Irish sire Yard Arm (b c 1843 Sheet
Anchor). Imported by Wilfredo Latham, Elcho entered the stud at cabaña
Los Alamos located at Quilmes (Buenos Aires).
mares were bred to Elcho, with Elcho's daughter Bella Donna
contributing to the establishment of this family as well as a
half-bred family through her daughter Bright Eye, the dam of the 1884 Clásico Criadores winner, Dichosa, who in turn produced Etoile, the winner of the Gran Premio Selección, Comparación, Producción
Nacional, Competencia, Luro and Primavera.
