From the size of Mum's bouquet I would say it is definitely the wedding of Mum & Dad. I believe the photo was taken in the back garden of George & Florence Ada Hall, Mum's parents on 25th August 1930. Elsie is to Dad's right with Len and Minnie to Mum's left. At the front left of the picture is, possibly, Doris or Lesley Titchmarsh, Beryl's sisters. I don't know the little girl to the right of the picture. If it is Mum & Dad's wedding then the title Wedding August 1932 is wrong.
