Robert Hobbs' (50yrs) occupation leapt out of the 1881 census, the Ag labs were gradually being replaced by railway workers, but the last thing you expect in Dogsthorpe is "Staff Sergeant, Bombay Army on Furlough".
His family comprised of wife Mary, 34, born Cork, Ireland.
Daughter Clara Elizabeth, 13, born Hydrabad Scinde, East Indies
Daughter Caroline Mary, 11, born Poona, East Indies
Daughter Susan Ellen, 9, born Belgami, East Indies
Checking the other census records I found Robert was originally from Ailsworth and from the 1851 census his parents were Robert b1800, and Susanah b 1791.
His stay in Dogsthorpe was quite short, by 1891 he had 2 further children James b 1882 in Dogsthorpe, and Agnes b 1883 in Ailsworth, Peterborough. His wife Mary had also died in 1883.
