Yes, I have some information from books I have about Hungarian nobility. Their name is: Izdenczy de Monostor, and they got their title (of baron) from
Ferdinand I, in 1566, because of their role in defending the frotress of
Eger. The title de Monostor, they became in the XVIII. Century (given to
Josef Izdenczy), who became in te same time: knight in the Order of St.Staphanus and 'Freiherr'.
