What we can tell you about Mio
Not every name has a meaning to trace. Plenty are coined rather than inherited — invented outright, blended from two names, or respelled from an older one — and where we cannot find an etymology we can stand behind, we would rather say so than make one up. What follows comes from the birth records themselves.
