I am trying to trace my family tree from my 3rd Gt Grandmother Susannah Stewart b.1793 London, England. Md.John Emery 11-2-1810 Marylebone,London. I have her parents as Alexander Stewart b.1761 London and Elizabeth Pickering Reid b.1761.Susannah's grandfather was David Stewart b.1740 London Md. Sarah Page 25-3-1760 and he died 1780 London. I have all records up until here but i can find no record for David's birth with his parents names. If anyone can help i would be greatful.
