I see the purpose of Debbie's question. There is a marriage in Toronto for a Sarah Gibson, 23, born Ireland, daughter of George Gibson and Alice Devilen who married William McKenna, 28, born Ireland, son of William McKenna and Rose Bradden on 22 May 1914 in Toronto.
I found a passenger list for an Alice Gibson, 20, who arrived in Quebec on the Melita on 12 Jun 1920. The passenger list indicates she was joining her sister, Mrs. McKenna in Toronto. The Form 30 she filled out indicates she was born in Belfast, was joining her sisters, Mrs. W. McKenna and Miss J. Gibson and her closest relative in the country she left behind was her brother, George Gibson of Belfast.
There is also a marriage for Alice Gibson, 24, born Ireland, daughter of George Gibson and Alice Devalin who married James Robertson McIntosh, 23, born Scotland, son of Hugh McIntosh and Maria Robertson on 4 Jun 1924 in Toronto.
