"Domnus Milo et uxor sua Litvisa" confirmed the donation of "terram de Ver" to Notre-Dame de Longpont, on the point of leaving for Jerusalem, confirmed by "filius meus Guido", by charter dated to [1095], later confirmed by "domnus Guido Trossellus et mater sua Letvisa". The Chronicon Mauriniacense records the foundation of the abbey, dated to [1095], and early donations including the donation of “ecclesias de Firmitate Balduini” made by “Guido Trosellus” with the consent of “uxore sua Adelaide et patre suo Milone vicecomite et matre sua vicecomitissa”. A supplementary section of the necrology of Longpont includes a reference to the anniversary of “donni Guidonis Trosselli et Mabilie uxoris ipsius XVII Kal Apr” and their donations, as well as to “anniversarius autem donni Milonis junioris fratris istius Guidonis...VI Kal Mai celebratitur cum Milone patre suo et Letuisa matre sua et Rainaldo episcopo fratre suo” as well as his donation.
