Hi there.
Actually, that blazon reads, "On a Mount Vert a Talbot sejant Or collared and lined Gules the lining fastened by a bow-knot to a Halberd erect Staff of the second Blade Argent". (Page 250 of my edition of "Fairbairn's Crests" - Tuttle edition dated 1968).

As mentioned elsewhere, there are also several other Hunt crests, but tracing ancestry via crests is not an exact science because crests can be changed at any time - it is the actual arms that are the important bit which can be traced to a finite point. Only properly evolved evidence of a documentary nature (a paternal pedigree) will let you know if what you are chasing is an actual fact or just another of those 'family myths'.

That actual crest is also ascribed to the following family surnames; Burgoyne, Colne, Colney, Gessors, Ghrimes, Hoofsteller, Horne, Norris, Plumbe, Sturges, Temple, Topliffe, and Toplis.
