Line of Sir John and Lady Jane Cuttle?

Hello all,
I am serching for the line of Sir John and Lady Jane Cuttle. They were my g.g.g.g.grandparents. Their daughter, Anne Cuttle, married my g.g.g.grandfather, Thomas Thompson Gilmore. Sir John Cuttle was a member of British parliament. I think the Gilmores and possibley the Cuttles wound up in Canada and then Maryland, USA. If anyone has any info on Sir John's line, his parents, grandparents, etc., it would be greatly appreciated, as would any info on the family of his wife, Lady Jane(I don't even know her maiden name!).
Thanks,
David Edelen
