18 Rue Philippe Lorand was the street address of Irma Dugard’s house in Paris, France, in 1927 (CG54).
Irma Dugard lives in the attic of the building. There is an entrance at the back that leads into a servant’s passageway and stairs leading upwards. At the top of the stairs is a landing with a door. The room beyond the door is the attic with “mended and freshly washed clothing hang from racks on the ceiling.”
Upon finding Irma Dugard’s name on his adoption papers, Credence Barebone and Nagini went to 18 Rue Philippe Lorand to meet the woman he thought was his biological mother. On arrival they found Irma Dugard in an attic room, sewing. She tells them that she had been a servant of the Lestranges and had been put in charge of taking Credence to America as an infant. Just as she revealed her secret, Gunnar Grimmson bursts into the room and kills her. In a tornado like fury Credence's Obscurus emerges and destroys the attic. Grimmson escapes by Disapparating (CG56).
Rue Philippe Lorand does not exist in modern Muggle Paris so we must presume that it was renamed some time after 1927 or it is the wizard name for a Muggle Street under a concealment charm.
