Dear Linda,
It would appear that you have the Tuckers in OZ well covered. As mentioned I have been able to trace the 2 sisters back to England and their parents and other siblings. However, there is a problem in getting copies of any documents to you as I don't know how to reduce the file size of each document and each one is generally too big to attach here, there being restrictions on the size allowed. If you don't already have my e-mail address, get in touch with Leeroy and ask him for it. If you then get in touch with me by e-mail, I can attach any records to a return e-mail.
Briefly, Richard Tucker was a Customs & Excise Man. He married Maria Smith at St Pancras on 2 May 1825. Because of his occupation, he moved around a bit, so the children were born in various places.
Richard, the first born, was baptised at St Pancras 3 December 1826.
William followed and was baptised at Battersea 10 August 1828 (born 14 July).
Maria Ann was baptised in South Moreton, Berkshire 11 July 1830 (IGI)
Jane was baptised in South Moreton, Berkshire 6 March 1832 (IGI)
Elizabeth was baptised in South Moreton, Berkshire 19 September 1833 (IGI) and appears to have died in infancy.
George was born in Newbury, Berkshire in ca. 1835.
Elizabeth was born in Glasgow, Scotland in ca. 1837.
Richard's wife, Maria dies between 1837 and 1841 as she does not appear on the 1841 Census, only the above children (except for the first Elizabeth) and a Female Servant, Hellen Allen. I mention this latter person, as in 1843, Richard marries her and starts a second family. I found 2 children to this marriage - Henry and Helen both born in Northamptonshire. This shows up on the 1851 Census with Maria and Elizabeth still living at home. What happens to Richard and Helen and their 2 children after 1851, I have been unable to determine, but they are no longer to be found in any of the later Census. Richard, could have emigrated somewhere, like his 2 daughters, Jane & Elizabeth.
In the 1851 Census, Richard and his brother William are living with a George Green & his wife Sarah. On Christmas day of 1851 Richard marries a Sarah Green, a daughter of a George Green and I suspect the same George Green that Richard and his brother were staying with earlier that year.
William Tucker went on to marry Janet Sutherland in Lanack, Scotland 6 June 1852 (IGI)
George went on to marry Frances Lennox in E. London, in the September quarter of 1859
In the 1851 Census, Jane is shown as being the 'daughter' of a John Tucker and his wife Sarah. But this is an error, and it should have been 'niece'. For on the following page and as part of the same family, Jane's brother George is listed and he is shown as being a nephew of John & Sarah. John Tucker & Sarah Hannah Ball were married in 1843 at Canonbury St Paul, Islington. John states his father as being Thomas Tucker, Clerk. When Richard married for the second time also in 1843, he also stated that his father was Thomas, but occupation Exciseman. No doubt the same father, and if Thomas was also an Exciseman, it probably explains why Richard was born in Ireland while John was born in Kent.
John Tucker was a Cabinet Maker as were Jane & Elizabeth's brothers.
I think That that is about the lot for now. Hope that you can follow it all OK,
Regards,
Bill
