My great grandfather, Matthew Ernest Guest, emigrated to Canada in 1904 on the Sicillian aged19 . He then came back during WW1 where he was a motor boat mechanic at various places around the UK, He met and married Winifred Dunstan who was from Falmouth. They married in Southampton in 1918. Matthew is then listed on the imperial gratuities as returning to Canada on SS Adriatic on March 1st 1919. I can't find him on this passenger list or Winfred on this list or any other going to Canada.
Would he have been with returning troops at this time so would she have travelled on another ship??
They then returned to England in Nov 1920 on the Empress of France with a child. He returned to Canada on his own in January 1921 whilst Winifred stayed in Falmouth.
Any help trying to find her records would be greatly appreciated.
