Here is an item from
http://www.ontariogenealogy.com/Victoria/townshipnames.html
which more or less says the same as a note I posted a couple of years ago.
Perhaps Trish would like to add it to her "Carden Places." John Surman
Carden was a member of the Tipperary Cardens, like myself. Best wishes to
all listers from Arthur Carden of Horsham, England.
Carden Township is named after Captain Carden, who, with Captain Digby and
others was complimented by General Hope, who took command when Sir John
Moore was killed at the battle of Corunna, for the unremitting exertions in
embarking the army with an expedition that had seldom been equalled. Major,
afterward Sir John Colborne (Lord Seaton) was at Corunna, and he was
afterwards, 1838-39. Governor-General of Canada. A street in Lindsay is
named after him.
Captain John Surman Carden commanded H.M.S. Macedonian when it was captured
by the American ship, United States, under Commodore Decatur, October 25th,
1812. Sir John Craven Carden, of Templemore, Tipperary, married the
grandmother of Lord Monck, who was Governor-General of Canada. His son
served at Waterloo.
