Send a message to the person who requested a photo of the grave monument of William with the following comment:
I am trying to locate my Great,Great Grandad, a William Gunby, we know through my extensive use of Ancestry.com that he lived in Bridge Street and Church Street in LLangollen but I wanted to find his grave from 1875, this is the nearest I have got to finding it! As I'm sure you know this can be frustrating, so near yet so far, at least I have the details of his houses from the two entries in the various census.Regards. Lorraine
