Cleaver was Granny Fannie's married name. My dad, Randall Delawder, Fannie's grandson, said her maiden name was Wolfe and that her full name was Wolfe-Cleaver, but because of the predjudices at that time, all the documents I have seen on her are listed as Cleaver. Not hyphenated Wolfe-.
If I find any more info, I will let you know. Email me at my email address.-Chris
