Yes, and sadly it didn't give much away at all. It looks as if she was born at her aunt's house in Bedford although the house number is wrong. Her father isn't there and the witness was the mother. So frustrating!
Sadly you are not giving much away AsH62.. on the birth certificate what address was she born at?, I take it that the father's name & occupation is blank, can you clarify if the mother's name was Beatrice Legg or Beatrice Beck or possibly Beatrice Legg formerly Beck; and what name did she use as informant. It is odd that Olive Gwendoline Legg is registered in June 1900 (born
4th April 1900) but the GRO index has mother's maiden name as Beck (unless it was re-registered after the marriage?); but this is a good 8 weeks before the marriage of Edmund Legg to Beatrice Beck on
31 May 1900 . Also I cannot see how she was 3 months pregnant at the marriage as next son Bernard Douglas was not born until 5th Oct 1901.
The marriage entry is on Ancestry (care of Dorset record office) & has Edmund Legg, policeman, residence Westbourne, Bournemouth... which is most likely where he joined the police force. The fact that Olive was born in Westbourne Road, Queens Park, Bedford is a coincidence & red herring.
