Hi
Not sure how much help this is, bearing in mind there are a number of surname variants, Powell, Powel, Pawell, Poell, Powle...
1858 March Q, Richard Powles, Cleobury Mortimer, registered death. V. 6a, P. 44. (Not too far from Ludlow)
Source, LPR:
8 Feb 1807 Richard, s. of Moses Powell and Ann, bap.
Ann's 2nd marriage appears to be 1871, not 1866, hence the uncertainty.
There are other records on family search and ancestry with similar output, though on balance 1814-1816 appears to be the mean DOB for Richard, which would render the LPR record invalid.
Regards
