Did the person Eugene Fürst (the editor) use the accent grave in his by-lines etc.? On the description page you may wish to write the name of the person as "Eugene Fürst" (even though the rose is 'Eugène Fürst').
I would like to know where the synonym "Prince Eugene" comes from? It's not in the references listed here on HMF. Also, there are various opinions about parentage in the references.
