I am trying to find information on Alexandra Mitchell(maiden name was McComiskey)and her husband John Mitchell travelling to America after 1904.Alexandra was born 22 Sept 1878 in Glasgow and John was born 1867 in Glasgow.They married 8 Dec 1897.I know that they were still in Scotland in 1901 as that is when my grandfather was born.I have been told that they travelled to America after 1904 but I am having trouble finding any records of them leaving Scotland.I know that my grandfather was definately in America as he married my grandmother there.I was hoping that someone would be able to help me with this problem.

Thanks in advance
Tracy
