I managed to find the images by searching Colsterworth Harris, although it would be more beneficial if the results linked to the actual images rather than just the first page of the register.

I've search Colsterworth Harris & got 83 image results.
Two of my main lines come from Lincolnshire, i'm off to play somemore on my names
