Let’s start with the name confusion. Thomas Miles Dunford is sometimes Thomas Miles Durnford.
He was born in about 1820 in Market Lavington. Sadly we have no 1841 census for Market Lavington or Easterton but we know that in 1849 Thomas married Eleanor Philpott and in 1851 Thomas was a gardener living in Easterton. Baby John was just 7 months old on census day.
By 1861 the couple had three children. They still lived in Easterton, possibly up on the sands.
At some point the family upped sticks and moved to Llandaff in the Cardiff area of Wales. Thomas was still gardening.
And he remained in Llandaff for the rest of his life. Eleanor died in 1881 but Thomas soldiered on, still gardening until 1899.
The photo here is of an older man so was probably taken in Wales. There is no photographer mark on this CDV sized photo
Eleanor also appears in a photo – this one a larger size but with no photographer’s name.
