Maria S Pavell is also on the employment and dispersal list for the 'Lord George Bentinck' which arr Port Phillip on 1 Apr 1849. The list notes her age as 22, occ: House Servant, and that she had 'Gone to her Brother at Melbourne'. The cost of her passage was defrayed by the Colonial Commissioners in full.
I'm presently transcribing these records.
Also, the Immigration Shipping Agent's list notes her native place, ie, where born, as Bramfield, Middlesex, her religion as Church of England and she could read and write.
