I'm guessing that Joestephia is an invented name, derived from Joseph/Josephine and Stephen/Stephanie, and given to a girl. Horestana looks like a similar invention, possibly based on
Orestes or
Horace, and once again applied to a female. Georgeita is an obvious feminization of
George, apparently by someone who liked adding "ita" better than using the name
Georgette,
Georgia, or
Georgine. Benjamina is a no-brainer--a feminine form of
Benjamin.
