Looking at passenger lists, there was a David McEwan , aged 16, of Liverpool, arrived Halifax Nova Scotia on the Aurania in March 1925. He was with a large number of children destined for the Marchmont Home, Belleville Ontario. They all are listed as coming from "Friend. Mrs Birt Sheltering Home, Myrtle Street, Liverpool".
David's name is endorsed with some handwriting that I can't quite make out.
"landing......." and a date
