During WWI all seven MAHWINNEY brothers of Montreal chose to serve. Two didn't make it home.
Robert, Thomas, William, Walter, David, John and Radcliffe MAWHINNEY were the sons of Radcliffe MAWHINNEY and Hannah Eliza BRASSINGTON who immigrated to Montreal from Lancashire, England c1905/06. ( see Mawhinney query )
John MAWHINNEY, born c.1898, in Bolton, Lancashire, England was killed April 27, 1915, while serving with the 2nd Brigade, Canadian Artillery Force. This was during the 2nd Battle, Ypres, Belgium. He is buried in the Ypres Town Cemetery Extension (Menin Gate).
Radcliffe MAWHINNEY, born c1896 in Lancashire, England, also served with the 2nd Brigade, Canadian Artillery Force. He died of his wounds on August 18, 1918. This was during the Battle of Amiens. He is buried in the Bouchoir New British Cemetery, France.
John and his brother Radcliffe had signed up together, as their regimental numbers are 41233 and 41222. It is also quite likely that Radcliffe may have been near John when he was killed as they served in the same unit.
