I was wondering if you had any info on Isabella Birkbeck that married Robert Spensley in Grinton on Nov 10 1836.
Meanwhile have you got the census stuff for Grinton for 1851/1861/1881...your Thomas and Jane are there with others who are probably related. I can let you have the info if not. (thats if it is your Thomas and Jane cos they've got lots more kids)
My ancestors are Siddill from Marrick and tie in with Spensley hence Isabella query.
