does the name augie march mean anything?

there are a few possible different answers here. First, Augie has the opportunity to change his name (he refuses); second, he feels his name has a destiny and equates it to Christopher Columbus (he discovers the meaning of what it means to be an American).

Augie (short for August?) (suggesting "augur"?)

August March, taking great strides,like Don Quixote, picaresque adventures; coming of age (from March to August), a" bildungsroman"

youthful and common (Augie, not Augustus), though eligible for greatness, constant movement and change, springing ahead (March)
