Hi Barbara
1841 census, I think Jane Byers age 30 was in Whitby with son Thomas age 2. I wonder why? I cannot make out what is written in the trade or profession column.
I think her age (59) is incorrect in 1851, I found a birth, IGI Jane Seaton christened 24 November 1810, Loftus, which fits. She would have been 39, 1851.
Also IGI found a Robert Byers Seaton born 1835 Guisborough - this could be the Robert Byers age 4 with Robert Seaton in Margrove Park Skelton 1841 census.
