Death & Funeral of Prince Henri, Count of Paris - 21 Jan. / 2 Feb. 2019

[Marengo]

It seems that the only other member if the Orleans family that was present was Pss Hélène, Css of Limburg-Stirum. It looks like the same church as the memorial mass of April 23rd which was attended by the Dss of Montpensier.

Is the man seated next to the dowager countess her son from her first marriage?
