Not NY or Boston, but my great grandfather and GG grandfather were both John Dwanes. Sr. was born in Mitchelstown, Cork Ireland around 1812, and was married to Mary Mahoney. They emigrated to Montreal, Quebec with several of their children around 1860-65. John Dwane Jr. (my great grandfather) was born in 1852 in Mitchelstown. He started a shoe company with his brother Timothy in Montreal.
