Thanks for answering this long-forgotten thread.
Lovely picture, and very poignant considering what was said about him.
I knew nothing of his condition, despite his early death could have been dictated by a poor health.
About his nephews.
Henri duke of Aumale had, at least 7 children, of which only 2 arrived to adulthood:
Louis-Philippe, pr. de Condé (1845-66) and
François, duke of Guise (1854-72)
I imagine there are photos of both and someone hopefully will post them.
What did they die of , one at 21, the other at 28 ?
