My 4th cousin 3 times removed, Michael Waddell married Jane Morrison Matthew in Glasgow in 1845, and had three children, including Robina Steele Waddell, born (according to the 1851 census) about 1849/50. Michael died before 31 December 1854, and Jane married, in 1855, Thomas Buxton, a surgeon from Tamworth.
They had five of a family. Thomas died in 1880, and Jane in 1912, in Tamworth. I have all the information I need on the Buxtons, who are not related to me, and on Michael's elder daughter Margaret. In particular I have birth references, marriage references and death references, and all relevant census records, for all except Robina.
In particular Robina S Waddell, said to be aged 46, and unmarried, was living with her half-brother Thomas Buxton and his wife and family in Tamworth in the 1901 census.
What I would like to know is whether Robina S Waddell, who died in Tamworth 1936/Q4/6b/439, allegedly aged 57, is in fact the daughter of Michael Waddell and Jane Morrison Matthews, who would actually have been aged about 87. If not, who is this Robina S Waddell, and what happened to her elder namesake?
