Hello Richard - I have birthdates of my great-grandfather (Thomas Frederick Bigg) and his family from 1833-1886.
Thomas was born in Poplar in 1883 and married Sophia Page in 1866. They had 10 children at least and all it seems, lived in Lambeth. Let me know if you want any more information.
I am looking for information on Thomas's parents.
D(Bigg) Harrison.
