There seem to have been quite a few George Smiths who painted. I haven't found the dates of this one - assuming these are all by the same person, which stylistically they appear to be (to my untutored eye).
As Cold Water is to a Thirsty Soul, So is Good News from a Far Country (1864)
Registering the First Born (1863)
The Eve of St Valentine (1871)
The Gamekeeper's Courtship
