Mary was born 1861 (1) in Westminster, Middlesex. She married Robert John Easterbrook in 1861 (2)

I can not find any trace of this couple after their marriage. They had at least one son as Mary's parents have a Grandson Harry Easterbrook living with them on the 1881 and 1891 Census. Mary's sister Gertrude had a son born in India and I do wonder if Mary and Robert went abroad.
