I am seeking help on where to go to reserach the birth record of an Emma Pellatt born 1834 in St Dunstan, Stepney, this information record on later censuses. Her mother also Emma Pellatt died about the time of her daughter's birth. I presume she was also living at St Dunstan, Stepney. I know this is pre 1837 and GRO records. Where would I go to research parish baptism and burial records?
