Irish Inspired Bride/groom Cocktail Names

Well you should first know that it's St. Paddy's day, not St. Patty's. Patty=Patricia. Paddy's=Patrick. After playing in an Irish band for years, this drives me nuts.

Love the theme. I think you could name them after places in Ireland. For example, the Cliffs of Moher for Jameson and Coke on the rocks. And for yours maybe the Majestic Shannon which is a river. Just make a sign posting what's in the them.

I would advise using counties or touristy locations in that case, I'm not creative but something about Dublin Down sounds like a groom's drink, or Give Me Moher/UnCork It might work.
Other locations I'm thinking of:
Ring of Kerry
Blarney Castle/Blarney Stone
Rattlin' Big (not a real location but a fun song!)
