Hi Rosie,
Mary was born 1844 and appears with her family: parents George and Mary and siblings John, Samuel, Martha and George in the 1851 census. Although Mary was born in Havant they have moved to Berkeley Street, Portsea by now. I THINK (but heaven knows how she got there) by 1861 Mary is in service to a Robert Carpenter in Stoke Damerel, Plymouth (I can't prove this is my Mary). After that I have her pretty well documented and proved. My problem is mainly her father - there are several George's that could be her father!
