Hi Michael
Just found this thread while trawling the net. Interesting!
Sarah Luxton b: 1837, was my gt gt grandmother, I believe she married a second time with Joseph Steer in 1870 and possibly a third time to Charles William Hall, in 1896. Sarah, may have died in 1908 as Sarah Hall, not confirmed. Any help appreciated here. I have snippets of info about Sarah's siblings, probably nothing compared to what you already have but you're welcome to share. I thought Ursula James was b: Launcells, but found another ref from Crediton, Devon, "I'm not that brilliant at this" I have no birthplace for John Luxton but he may have been at Barnstable, Devon, in 1841 Census. I have listed all the children as born in Kingston district though, Hmm. I would have got this from census but I don't currently have an Ancestry sub so can't recheck
Some of my info was found sometime ago so not entirely sure of some sources. I got a bit bogged down and moved on.
