julstaurus on Family Tree Circles

I am currently researching Mary Wade who was shipped to Australia in about 1790, i think, aboard the Lady Julian convict ship. She was born in Southwark, London in 1777 and her parents names were George Wade and Mary English. If anyone has any information on Marys parents or any information on the family before them, including their life in London, it would be much appreciated. Thankyou.
