Samuel Collins age 28 burial 23 May 1861 St Bartholomew, Wednesbury
COLLINS, SAMUEL 28
GRO Reference: 1861 J Quarter in WEST BROMWICH Volume 06B Page 395
I note the burial for Ann in Kingswinford 7 miles from Wednesbury, sadly it is not on freereg.
There is a burial for Ann in Wednesbury in 1869, freereg but the age is wrong, unless it is an error.
I do not see a GRO index for Ann in Staffordshire; the only one in Q3 1865 West Bromwich is age 0. None in Q4?
