Some St Patrick facts.
He was really Scottish [some sources will say British]
He was kidnapped [when a child] by Irish raiders who took him back to Ireland and forced him into slavery.
He escaped years later and made it home and then went to Rome and became a priest and later was sent to Ireland as a bishop to convert the isle from paganism.
He is a saint for converting the Irish to Christianity [Catholicism specifically] AND there were never any snakes in Ireland.
Remember, the truth will set you free
