Hi Liffyb,
My partner is a direct descendant of William Nelson, and I found Lucilla working in a pub in the 1881 census where she was listed as Servant, or could this be 'barmaid' age 19, and a birthplace as NK (meaning Not Known), India.
This was the 'Cow & Hare' in Heigham St, Norwich. My guess was she met William as a customer in the pub. They married in 1884 and gave her occupation as a Silk Winder, and her father as Charles Mullins (deceased). My next guess is she was illiterate (as most were at that time), and couldn't read what was being entered in any case, even if she knew the difference between the West Indies & India.
She and William had 5 children, one of which was my partners grandfather. Other branches of the family still live in the Norwich area. Also of interest is that his father was lilled in an explosion in a Norwich street in 1876, and a distant member of the family sent me a copy of the newspaper report.
