I found a genealogy that cautiously links the Rougemont with the Rosemont of Bois-De-Luc. With Lehamn Rosamond’s little book, this link can be made. When the Habsburgs came to rule Rougemont, they spelled in Roozmont. Roosmont in another spelling for Rosemont/Roesmont.

“As a WEAPON this conducts line Roesmont: on a golden field a climbing wolf of sabel.”

The Roelof name is Rudolph and Rollo, meaning “famous wolf”. The Roesmont cote of arms is a wolf with the words Bois-D-Luc underneath, which means “Duke of the Woods”. Wolf House belonged to Herny 1 Duke of Bradant, the son of Mary of Champage who was the patron of Chreiten de Troyes who authored Arthurian Legends.
