Here is a postscript to the earlier discussion of Habsburg bastards. N.B. that the remains no evidence of ANY after 1618 or before 1800.
"Emperor Rudolf II (1552-1612), who never married, had 6 illegitimate children, all titled Markgraf or Markgraefin of Austria: Dorothea (a nun), Elizabeth (a nun), Karl (a soldier), Julius (born about 1586) Herr von Krummau who became insane and died 1609 at Krummau. The last two were by Euphemia von Rosenthal: Matthias who, in 1608, hoped to become a Cardinal; he didn't, joined the army and in 1618 married a "Sicilian princess", died in Germany in 1626. Charlotte died in Mechelen (now in Belgium) in 1662; in 1608 she married Francois Thomas d'Oizelet, Comte de Cantecroy.
