Thomas McGown is the patriarch of the Canadian McGown's that I am tracing.  He was born in 1801 in Lanarkshire, Scotland.  He married Margaret McNaughton in 1822.  In 1841 they lived on Struthers Street in Barony Middle Calton, Lanarkshire.  Thomas was a 'cotton piercer dresser'.  They migrated to Canada in 1844 and settled in Otonabee Township, Peterborough County, Ontario were Thomas was a weaver.

They moved to St. Vincent Township in Grey County by 1861 where Thomas continued working as a weaver.
