Jenny,
hope you don't mind my putting in a request on your behalf as it is to help with details from your other enquiry.
I am thinking that the John and Ann Wilcock both age 60 are Thomas' parents.
Being John Wilcock and Ann Booth who married at Kildwick in 1798. having a son Thomas in 1799. and being from Silsden.
Could someone please find them, John and Ann Wilcock, in the 1851 so we might get some more details on them please.
thanks
Margaret
