Steven, if they are Leo's cousins (Henry Leopold Bryceson 1893-1957), they would need to be children of his father's siblings, OR his mother's siblings.
Got 'em
Edie, is Edith Sarah Stangroom, daughter of Sarah Maria BRYCESON & Walter STANGROOM
Florrie, is sister to Edith, Florence Ethel Stangroom
Stan, is Edith's husband, Stanley Ernest Atwell (not a relation to Lucy Mabel Atwell by any chance??)
and Edie's mum - Sarah Maria Brycson!! NB's daughter!
Haven't figured out who the boy is though
