Daniel Regan - left 1823 with Peter Robinson Settlers to Canada

I've recently learned that Daniel Regan and his six children left from Cork in 1823 with the Peter Robinson Settlers going to Canada.  He was married 2x: Judy Carney 1783-1811; Julia Greer 1780-1821 who both died I believe in connection to child birth.  I've learned thru Charleville Heritage Society that a group of people who left on this emigration journey, included Daniel.

He may have been born in Ballyshehan 1775; his first son John was born 1806 in Killavullen.  Sponsors to baptism are: Thomas Fin and Elizabeth Magner.

Any suggestions to assist in locating family left behind would be greatly appreciated.  Cheers, Linda
