dgcgeni on Family Tree Circles

I am desperate to find parents of Great,Great grandfather Jonathan Crabtree born 1821 Hebden Bridge. Married to Jane Ellison 1845 in Bishop Auckland, Durham England. He was apparently also co-habitating with a Mary Allison born about 1823 in Yorkshire I think.

Would like to trace ancestors from him onwards as I have hit a brick wall. I have his marriage Certificate for Jane where it is witnessed by his father WILLIAM.
Any copies of Birth, Marriage, Death Certs would be very, very much appreciated.
