David Bewes explains:

Ringwell House was built by Richard Leir (1772 - 1850) for his own occupation. He was a barrister, but never married, and must have rattled around on his own! At some time after his death his nieces, daughters of Rev William Leir (1768 - 1863), took the property over. They were Charlotte Leir (1809 - 1898), Emma Frances Davies, nee Leir, (1813 - 1892), and Elizabeth Leir (1808 - 1898), who was deaf and dumb from birth,. The three sisters were affectionately known as "The Ladies of Ringwell", and in 1909 a window was erected at St Mary Magdalene, Ditcheat in their memory. Elizabeth and Charlotte were in residence at Ringwell House at the time of the 1871 census.

Rev Charles Edward Leir (1842 - 1924) moved into Ringwell House in 1893, and it became the Rectory until 1938, when the present Rectory was built.

I am afraid I cannot identify the other people in the photograph. Clearly there is the gardener and his boy. There is also another lady, - it could well be the other sister. But I do not know who the gentleman is.
