The open source character of Miss May, created by Corey Grant, has been released to the Public Domain, and is available for use by anyone with only the following conditions: this paragraph must be included in any publication involving Miss May, in order that others may use this property as they wish, following the same rules as Public Domain properties. The main rule being that your version's story cannot be like the story of anyone else's version (meaning: you may not reference elements from the story you find the character in, because they belong to that story's author, and are not open source).

There are no "Miss May" or "Mayweather Lopez" characters listed on Comic Vine, so as far as I can tell, the names are not being used in comics. Therefore, they're viable as Open Source Characters.

Miss May is a common title for calendar models who appear on the May page of a calendar, and it's reasonable to assume that someone else may come up with the idea separate from this OSC.
