Also called Smith's Son of Snake, he was bred in North Yorkshire by Mr Smith, and was a twin (???) to Williams Squirrel. He was referred to as Mr Ellerker's Easby Snake in Cuthbert Routh's stud book Smith's Son Of Snake
This horse was not identified as Easby Snake until the 1891 edition of the General Stud Book, and the identification is probably incorrect [GSB 1/5:1]. Easby Snake may well have been Ellerker's Snake.
