• Not sourced or known daughter of Frederick II, Duke of Swabia & Agnes of Saarbrücken
• Not sourced or known wife of Aimone d'Aquino, count of Acerra
• Not sourced or known mother of conte Landolfo I d'Aquino
• Not the same as wife of Aimone d'Aquino, count of Acerra

given the type of links to old DIY ones which are also no longer working, this really seems to be an abusive fantasy node for Saint Thomas of Aquino.

Note: The pedigree that I originally got Francoise de Hohenstauffen from, J.K. Loren, World Connect db=lorenfamily, had her as the 2nd wife of Rinaldo d'Aquino, and mother of Aimone. This did not fit with Turton & SGM, which indicated that Rinaldo only had one wife, who was mother of both Aimone & Sibyl. However, several websites containing books on the life of Thomas Aquinas (see notes under him) indicate that it was Thomas' grandfather (ie. Aimone) who married a sister of Frederick I Barbarossa HRE, although they do not name the grandfather or his wife. None of my normal sources give a wife for Aimone/Aymon.

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.
