I have traced my great-great grandfather and he was a butler on the 1881 census in London but ten years earlier in 1871 he is living in a different household in Ascot and is described as "Butler, Private Coldstream Guards". The head of the household's son-in-law is Christopher Edward Blackett who is living at home and described as a "Cpt & Lieut Cl Coldstream Guards".
I know that servants often served in the army with their masters and were usually called a valet or a batman. But here he is described as a butler and is at his masters home (or at least his mother-in-law's). Was this the normal practice? And does that mean that he traveled everywhere with him whether on active service or not?
Also although he is described as unmarried he had actually married the previous year. His wife is working as a cook in a different house in Hampshire in 1871 and is described as married. Was this unusual? I now that servants weren't usually permitted to marry except in the case of butlers and cooks but usually in the same household. And as he was also a soldier this may have added complications. Can anyone offer any advice?
