Taken from a blog:
From the Times obituary of Archduke Felix of Austria, who has died at
the age of 95: "Felix Friedrich August Maria vom Siege Franz Joseph
Peter Karl Anton Robert Otto Pius Michael Benedikt Sebastian Ignatius
Marcus d'Aviano of Habsburg-Lorraine … was named after his uncle Felix."
His mother had eight children, but presumably had to stop when they ran
out of names.
P.S. Is there anyone out there who thinks that TWL's Archduke was someone
other than Rudolf?
