I came to the same conclusion as majm, rendering it as Tobie Mile, so I searched GRO indexes and 1871 census using Tob* Mil* and using the dates as given and haven't been able to find a thing other than the find a grave reference.
If we go back to the theory that it might be a re-mounted picture then it could have come from anywhere, Scotland, Ireland, Canada, America, India, Australia etc. sent to a relative "back home".
