Thank you for all your replies. I started this thread off looking for more information on the younger Jane, but am also trying to find data on the older Jane, or rather her father James. I understood from my late aunt's notes that he was the son of Robert Owens, 1777-1860, but another tree has him as the son of John Owens, 1772-1857. This tree does have Jane 1843 as the daughter of James 1814-1896. Yet another tree has James as the son of Robert, but doesn't have Jane 1843. To complicate things further, James 1814-1896 in his will mentions only a son William and no other family apart from his wife.
I can see a Samuel Owens in the 1901 census entry, but he is listed as a servant rather than a nephew.
