Really, that is interesting astral.
I have Lemontaney as the youngest child of Thomas Carey and Caroline Pateman. She was named for her aunt Lamatina, and born on 6th August 1849, in the village of Stanwell, Middlesex. The birth cert is registered as Clementina Carey, but she was baptised as Lemontaney Carey, at thirteen days of age, at St Mary's Church in Colnbrook, Buckinghamshire, on 19th August 1849. She later partnered Job Parker, son of John Parker and Selina Halford/Alford, and appears recorded variously as 'Lemio' (Apr 1871) 'Lamantana' (July 1871) 'Lamtannay' (Apr 1881) 'Clementina' (Oct 1884) and 'Lemington' (Apr 1901). In April 1911 as Clemintina Parker, she is recorded with Job, in a tent on Horsley Common, Surrey, stopping with Coopers, Marneys, Junixs, Vinsons, Deacons and Gobys. Her death, in a caravan at West End, Esher, Surrey, in August 1920, was registered as Lamentany Parker, the sixty-eight-year-old wife of Job Parker, a ‘Licensed Pedlar’.
I know she had an older brother John Carey, who married Rebecca Harris, in August 1863, at Epsom, Surrey, with Matilda Parker as a witness. Is that the link?
