Many thanks to the replies I have had regarding Winifred Link.  She did well in Canada because she was a Home Child sent out ona ship in 1912 a couple of months after the Titanic went down.  About 120 Barnardo's children also on the ship.  Her mother - my paternal grandmother - died in London in 1904 and with other family members lived in Ipswich orphanage.  Don't we have easier lives now.
Best wishes to all for the information.
