Certainly does for the Irish.. we know nobody name Patty!!!
That is excellent for them, but when it makes reference to the Patron Saint of Ireland, or any Irishman for that matter, it's Paddy.
The name Patrick in Irish Gaelic is Padraig.
Paddy is Irish short for Patrick... whereas Patty is more likely to be interpreted as a refreshing peppermint chocolate treat or a Jamaican Pastry delicacy that may have either meat, chicken or vegetables within.
Happy belated St. Paddy's day... March 18th was a write off for me.
