Emily Reilly

Hi Everyone, 

Wondering if anyone can help with this. My great aunt, Emily Reilly was born 19/09/1900 to parents William Reilly & Julia Fagan. I have located them on the 1911 census and I know she was a witness at my uncles baptism in 1936. It\s the time in between and after I'm interested in. I know that she went to Canada (apparently in the 1950's but I can't find her on any passenger lists). She apparently also had a child called Nancy (no idea when). My aunt said she went by the name 'Emily Armstrong' so I'm assuming she married someone - my aunt has no idea but thinks the father of Nancy was English. Does anyone have any idea where to look from here? Thanks Christine
