It has been most kind of you to answer my question. Now I remember reading about the broken engagement between Prince Jean, Duke of Vendome, and HH Duchess Tatjana of Oldenburg. As far as I understood, Count of Paris "feared the Orléans claim to the throne would be compromised if there was a Protestant heir". I was and am shocked to see such display of the mauvais ton on the part of Prince Jean. In the end, it may be for the better that HH Duchess Tatjana did not join the feuding family.
"To watch the sun sink behind a flower clad hill.
To wander on in a huge forest without thought of return. To stand upon the shore and gaze after a boat that disappears behind distant islands. To contemplate the flight of wild geese seen and lost among the clouds.
And, subtle shadows of bamboo on bamboo." Zeami Motokiyo
