When Kent and I toured the Jameson Distillery, toward the end of the exhibit there was a board containing the names of the coopers and the nicknames they ended up getting. I figured Kent's last name would be there, or his paternal grandmother's name (Ahern, definitely Irish) but they weren't. Instead and to my surprise, I saw the name Jordan.
My older son is named Jordan which in and of itself doesn't mean much. But he's named after my grandfather, who was in turn named after his grandmother -- that was his grandmother's maiden name. So who knows . . . maybe somewhere in the European mutt mix that is me, a thread of Irish DNA lurks.
