What years did your Gt Grandfather work there as a butler?
Does he appear on a census as a live in Butler?
Do you know the name of the family he worked for?
If the house he worked at or the family he worked for can be found on a census or electoral roll then it may be possible for Mike Jee our map expert to find the location of the house on an old Map and then see if it is still there.
If you give as much information as possible - someone on here may be able to help.
Yes I have him on all of the census records, even 1891 where his birth year has been transcribed incorrectly. He was shown as a scholar in 1841 in Ockbrook which was/is a Moravian Settlement. I don't think the picture is from Ockbrook as I have visited the Settlement and found a large number of Drennen graves.
I assume he moved from Fillongley Hall to Leamington when he married in 1879. Buried in the minutia of his accounts, I have found mention of these places / dates
May 1882 moved to 5 Southwick Crescent, Hyde Park, London - Mr Cohen
Feb 1885 mention of St Leonards
Aug 1885 mention of Banstead
Feb 1886 mention of St Leonards
Aug 1886 mention of Banstead
Feb 1887 mention of 5 Southwick Crescent
Jun 1887 moved to Bennington Park in Campbell although Campbell may well have been a person's name
Apr 1889 came to Dover to Mrs Heygates service and came to the Oaklands Herefordshire.
Think I need a good stroll around the Docklow area!
