Hi Sue
I have quite a bit of information about The Nickolls, Wilkins and Webster families. h Charlotte Wilkins was from Bath, her parents were Charlotte Webster, from Deene, Northamptonshire, and Rev. Thomas Wilkins of Weston, nr Bath. My husband is a direct descendant of Henry Nickolls and Charlotte Wilkins. Charlotte is described as being "from this parish" (Tansor) on the marriage record presumably because she was staying with her mother's Webster family, who were from that area.(Charlotte Wilkins' maternal grandparents were John Webster and Elizabeth Dexter, both deceased at the time of this wedding, 1826) Charlotte Wilkins was born in 1798 in Bath, Somerset (bapt 5 April 1798, St Michael, Bath) and Henry Nickolls (the "k"is the correct spelling) was born in Little Stukely, Huntingdonshire (bapt 1 January 1794, St Martin, Little Stukely). Henry and Charlotte emigrated to Tasmania (then Van Diemens Land) in 1827, per the "Admiral Cockburn". I have not found as yet any other reference to a Berkeley in the family, other than it being the middle name they gave their son Henry. It may have been a friend's, godfather's or mentor's name of course and not a family name.
Henry Nickolls' parents were John Nickolls, born Buckworth , Hunts, in 1765 and Millicent Martin, born Elton, Hunts, in 1769. I haven't found their marriage yet but their first child was Henry, so I guess they married in about 1793 or earlier. John Nickolls died 11 May 1845 and Millicent died 30 Dec 1837. They are both buried in the churchyard of St Mary's , Buckden, Hunts (now Cambridgeshire). I have visited St Mary's and photographed their gravestones.
Please let me know what else I can help you with.
