That's a good question. Proof for this one will be difficult.
Family names tend to indicate this though. One son is named Richard Menefee and one son is named John Malrey/Mallory? Menefee.
Also Elizabeth Menefee Chapman (daughter of Henry and Sarah Dollins? Menefee) named a son John MALERY Chapman. Another daughter Hannah Menefee named a son MALLORY Corbin. Another daughter Frances Menefee named a son William DOLLINS Partlow.
