TROLLOPE
As described in historical dictionaries
Patronymica Britannica (1860)
TROLLOPE. A name of uncertain derivation. A long-standing tradition in the family makes it TroU Loups, in consequence of some marvellous exploit performed by an early progenitor against the wolves which then infested Lincolnshire; but as the name has been spelt Trowlop, Trolop, and 1x0102)0, I have little doubt of its belonging to the local class, although the place from which it was assumed has been forgotten. See Hope. The family of the baronet are ancient in Lincolnshire.
