From A history and description, with reminiscences, of the fox terrier (1895), Author: Lee, Rawdon B:
Tartar's pedigree, as given in the first volume of the Stud Book is open to great doubt, though it is said he was bred by Mr. Stevenson, of Chester, about 1862 from Weaver's Viper out of Donville Poole's Touch. I think there is little doubt that he was a cross-bred dog, for, he was shown at Birmingham in 1863 pedigreeless, and had those who looked after him cared to determine his parentage (or if they possessed it to publish it), they could easily have done so at that time and not waited until the dog had gained a reputation.
