While the Maier family owns two castles (and 15 vineyards) in France, it appears that the duke and duchess will be staying in the New York/New Jersey area as Maier is currently the longtime managing director at Speyside Equity in New York City.

This is Staub’s 21st enagagement.

“I’m madly in love,” Staub told People. “I’m feeling elated and excited for the next stage of my life. I’m going to marry the man of my possible dreams and hopefully I’ll spend the rest of my life in bliss.”

The happy couple plans to get married during a small justice of the peace ceremony in New York City on March 4th with “Real Housewives” co-star Teresa Giudice.
