Hi all, I am again coming for pointers about my elusive ggf's even more elusive ancestry

I have come to a brick wall trying to find anything about my 5x ggm, Mary Bartholomay. I only have her marriage to Jonathan Hurst (1786-1850) in Leigh, Lancashire, England, on 19 Aug 1807 (FHL 1885651 p112) and the fact that she had a daughter, Mary Hurst (b. 24 Sep 1820 Deane, Lancashire, England-Dec 1861).
I would love to find out who her parents and further relatives were, I was intrigued by her maiden name

Thank you in advance,
