"I found several unsourced entries on the web that gave as Aimone d'Aquino's mother, a Francoise von Hohenstauffen, half sister of Emperor Frederick I, being daughter of Frederick von Hohenstauffen, Duke of Swabia by his 2nd wife Agnes von Saarbrucken. .... "

"I think you're right to be suspicious. "Francoise" is indeed a much later name, that did not come into fashion (and is not found in any royal house) before the canonization of Francis of Assissi two generations later. It is possible that a Hohenstaufen had an unmentioned illegitimate daughter who married a minor nobleman of southern Italy -- Frederick II was masterful in arranging such marriages for his bastards -- but legitimate daughters are all pretty carefully tracked."
