I have found even more information about this family, including the baptisms of all the children on the IGI. Maybe someone may be able to assist with some of the marriages:-
William Lucas (b. 4.1.1736 London) married Elizabeth DeNeufville (b. 1743) on 8.11.1764 in Soho, London. His parents were Rev. William Lucas and Elizabeth Knight. Her mother's maiden name was Bosville.
William and Elizabeth had the following children:-
- William Knight bap 1.7.1766 St Andrew Undershaft, London, died before 1769
- William bap 1.2.1769 St Andrew Undershaft, London
- Phillip Thomas bap 28.6.1771 St Andrew Undershaft, London, died before 1774
- Sarah bap 17.12.1772 St Andrew Undershaft, London, married a man by the last name of LEE

- Frances bap 16.8.1780St Olave Hart Street, London, married a man by the last name of Clifton
- John bap 15.8.1782St Olave Hart Street, London
I am trying to prove the connection to a Robert Lucas (born cira 1799) who married Jane Moon on 23.9.1819 in Trowbridge, Wiltshire. They had a son called DeNeufville and moved to Australia. DeNeufville referred to his father as Robert DeNeufville Lucas. Any assistance anyone can provide would be greatly appreciated.
