Minnesota callanan clan

Hello,

I am looking to hopefully connect with some unknown relatives when i visit ireland for the first time this summer. my great-great-grandfathers name was john callanan, he was from dalystown area near loughrea then emigrated to america in 1850 at age 18, so he wouldve been boren in 1832, thank you kindly for your time and effort to assist me in completing my family tree:)
