we went to parwich a few years back - William was related to one of my husbands ancestors.The information I have is: William Greatorex (Farmer) b. abt 1781 (christened 2nd April 1781), d:22nd December 1865. Married Sarah Toplis of Brassington.Children: Lydia(mar. John Kirkham - children Lydia and John Toplis Greatorex), Thomas (b. 1817 mar.Ann Webster - children Thomas, Betsy, Lidia, Lucy Ann, William, Alice and Wright), Sarah, Henry, george, Joseph and Eliza.
I have a lot more information on the family - plus a few photos of Parwich churchyard and (I think) either Williams's grave or those of his sons Henry and george who both died in 1853.i will try to find them for you if they are of interest.
