Now I'm searching where the name Sugden comes from!
I believe this is Robert and Grace's marriage:
Jun 1863 Skipton 9a 48
Robert Jackson - Grace Baron
I can't see Robert as Sugden until 1871. In 1861, the best match I can see for Robert is at Farnhill, a Robert Jackson age 21 (born Farnhill) lodging with a William Sugden
(there are other Sugdens in the neighbourhood)
RG9/3186 90 15
Not sure where to go from there yet

Added:
Aha! 10 years earlier, Robert Jackson age 11 born Sutton is already visiting the same William Sugden (then aged 43) in Kildwick!
