OP, I'm all for you expanding your options and marrying who you want. However, you're sort of late to the party and you're limiting yourself in regards to the old money guys. Most women who want these type of men have been groom from birth and find them at the various social functions that they attend. Old money families only associate with other old money families. They keep a tight leash on their children and raise them in a bubble. Like someone mentioned above, why not try to connect with new money men or just men who you have things in common with? Why limit yourself with a pool of men that are beyond your reach? There are many upper class and educated men of various ethnicities who don't belong to the old money crowd. I understand where you're coming from and that you want to have a certain lifestyle. There is nothing wrong with that. I just think that you could find that lifestyle without going through the hassle of having a WASP husband.
I recommend that you read, "Swirling How to Date, Mate and Relate Mixing Race, Culture, and Creed" by Christelyn D Karazin and Janice Rhoshalle Littlejohn. Also, Christelyn has a blog specially for African American who are interracially married or who date interracially called, "Beyond Black and White"
http://www.beyondblackwhite.com and there is Facebook page as well. I think it would be great for you to connect with other African American women who are interracially married.

Also, checkout the Loving Day
http://www.lovingday.org website. We have a big Loving Day celebration in NYC every June. If you don't mind the travel, we have tons of Loving Day workshops and events in NYC throughout the year. I honestly think the folks in NYC don't have as many hangups about interracial relationships like the folks here in DC do.
Goodluck OP!
