Thank you, Milliepede! I had seen a reference to Bartholomew in other ancestry.com family trees but did not know the source, nor that he was a sailor. A Bartholomew Foot appears in the 1841 census of Shaston St. Peters ED4, 60 years old, a weaver. With him is Martha, also 60 years (presumably his wife), John a stone mason, aged 20, Louisa, also 20, and Charles, 2 weeks. It's tempting to make the connection, but Louisa is clearly not Jane, so this raises more questions than provides answers.
