John Thomas Gleason (s/o Thomas & Emily Breen) was my husband's 1st cousin once removed. In fact my hasband was named after this individual.
John Thomas' sister Emily Bridget (nee Gleason) Kavanagh married and raised her family in Emmett, St. Clair Co., MI. There are 7 Kavanagh boys from this union. Many descendants still remain in Emmett to this day.
If you give me an e-mail address I will see if I can put you in touch with some of them.
