Edith Grace Glyn married a Charles Edward Briggs (a clergyman !) at St Andrew’s Well Street, St Marylebone, Westminster on June 9, 1903. According to the marriage register (viewable on An***try) there were no marriages performed between June 20, 1903 and July 16, 1903
Cecil & Edith’s father, Richard Henry GLYN was also a commission agent, born in Quebec. He died in 1913 and his probate indicates an estate of approximately pounds 65000.00 – a lot of money now and even more in 1913

I don’t have access but he is mentioned on New York Passenger Lists.
