I now have confirmation that Mary Dewhurst m. Richard Kilburn, 2nd November 1851 at the Parish Church, Walton-on-the-Hill, Liverpool. Mary was the daughter of Henry Dewhurst, plasterer, Liverpool. Witness was Margaret Dewhurst.
Looking at the 1851 Census there is only one family that fits this criteria. It is highly likely that we have common ancestors. I don't have much information prior to this event, but will gladly share what I know.
