Thomas Nelson BONNER - Ireland to USA Jan 1833

I am searching for information on the family of Thomas Nelson BONNER my GGGgrandfather.  His USA naturalization records state he was born on the 15th of October 1826 in Dublin, Ireland.  He left Ireland in November 1832 and arrived at St. John New Brunswick, Canada, in December 1832, and from there he arrived in Calais, Maine, USA, on January 25, 1833.  He made Eastport, Maine, USA his home until his death around 1856-1860. This scant information is all that I have on his origins.

Thank you so much.
