[2] The Hôtel was last owned by Jacques-Donatien Le Ray de Chaumont, who bought it in 1776 and rented to Benjamin Franklin the dwelling appending by the orangery, and eventually the eastern pavilion of the Hôtel.
[3] Le Ray de Chaumont sold the Hôtel as three different lots.
[4] Auguste Doniol's claim that in June 1837 the Brothers of the Christian Schools bought "les deux pavillons" (supposedly those bordering present-day Rue Raynouard), and a part of the gardens, from "M. Briant"[5] seems to conflict with Henri Bouchot's claim that Briant had owned "the back premises" (likely the orangery and adjoined buildings) "and kitchen-garden", while "the greater part, the house with the colonnades, the terraces and garden" had been owned by "writer and politician, Claude Fulchiron of Lyons",[4] and with claims that these passed in 1811, at least in part, to banker Isaac-Louis Grivel's daughter Anne-Marie, and were sold by her husband Charles Vernes to the Brothers in 1836,[6] another part having been bought by industrialist David Singer and opened with a street bearing his name as early as 1836.
[7] A "third lot" had fallen "to Du Mersan, the gay dramatist", comprising the commons and some remains of the garden[4] (likely a southwestern part of it, visible on the Roussel map of Paris and its faubourgs and surroundings but not shown on the Guélin plan of the Hôtel).
On 8 April 1839, the Brothers transferred a boarding school for boys which they had opened at 165 Rue du Faubourg Saint-Martin to facilities which they had specially built on their lot of the Hôtel's grounds and possibly facilities of the allotted Hôtel which they had preserved,[8] and which became known as "le Pensionnat des Frères des écoles chrétiennes à Passy".
