Enterprise held it`s annual one man, St. Patricks Day parade yesterday...Patrick John Michael Donahue made his way through Enterprise as loyal and non irish alike, joined in the fun. The Shamrock Club of The Progressive City, conducts this event each year for citizens with Irish ancestry, but all are encouraged to take part in the parade. Millions of Americans trace their ancestry back to Ireland, and advertise their ties by wearing their green on St. Patricks Day, March 17th. There are 34 million U. S. residents who claim their Irish heritage. This number is almost nine times the population of Ireland. Irish is the nations most used ancestry, trailing only Germany.
