Hi Val,
It suddenly occurred to me that I could do a couple of relevent lookups for William & Mary WILKINS.
Louisa Ellen WILKINS bap. 5th April 1820, at St James, Bristol. Register 2b, Page 184, Number 1471.
William WILKINS, Bachelor, of this parish, m. Mary BRIDGE, Spinster, of this parish, 4th July 1816, at St John, Bedminster, Bristol. Register 3f, Page 162, Number 485.
Hope that helps?
Victor
