A few odds and ends which may be connected:
Before Filkins had its own church, the inhabitants often used the parish church at Broughton Poggs.
There is only one TOWNSEND baptism at Broughton P. in the time frame 1790-1820. This is Sophia, baptised 13 April 1806 d/o Daniel and Elizabeth Townsend of Filkins.
Sophia Townsend married Edmund Lane at St Mary de Lode, Gloucester 20 June 1822 (by banns)
Sophia Lane, born Filkins c 1808/9 shows up in censuses living at Chedworth (1841), Sevenhampton (1851) and Cheltenham (1861). She is recorded as married in 1851, widowed in 1861, but Edmund doesn't show up with her at all.
A Daniel Townsend aged 66 was buried at Withington 27 December 1826. (Gloucestershire Burial index)
Theyer and Elizabeth Townsend had a son named Daniel baptised at Chedworth on21 May 1837 (familysearch.org). A 3 year old Daniel Townsend was buried at Chedworth 16 April 1840.
Daniel seems to have been their eldest son. Their eldest daughter is named Elizabeth.
