I don't know if this is of use to you. I was given most of it on RootsChat a few years ago.
Here is a summary of what I have for Martha Jackson:
Born~1837 Belton Lincs
1841 Belton Lincs
1851 Thorne Yorks
1861 Belton Lincs in Kettlewell family
1871 Armthorpe Yorks 5 chn born Belton Armthorpe and Doncaster
1881 Scotton Lincs with Richard Kettlewell and 6 chn
1891 Messingham Lincs “widow”with 3 chn

I can find 9 chn in all: 7 Jacksons and 2 Kettlewells
All the best
