Why would you assume Currie's parents were ignorant immigrants? They didn't changed the spelling of Curry to Currie . Sir Arthur Curry did.
As you said, "Interesting geneology, by spelling?" Yet you claim Strathroy was settled by Scots so Currie must be a Scot . As if that makes one bit of difference .
Well , you'd lose your bet. Currie's Grandfather's name was John Corrigan who emigrated to Canada in 1838 and changed his name to Curry . Corrigan is an Irish name .
