LAUREN BUSH MERGER: Hometown girl, Margo Morton Langenberg, daughter of the late investment banker Harry Langenberg and Lucian, was at the wedding of the summer on Sunday. She watched as model Lauren Bush, 27, niece of George W. and granddaughter of George H. W., officially became Lauren Bush-Lauren, when she said "I do" to David Lauren, 39, son of Ralph (yes, that Ralph Lauren) and Ricky Lauren.

The wedding on the Lauren's 17,000 acre Double RL ranch near Telluride, Colo., capped a weekend of festivities, which included a picnic, baseball game, rodeo and rehearsal dinner. The bride arrived for the wedding ceremony in a horse-drawn carriage wearing a Victorian-inspired lace gown designed by her new father-in-law.

She was escorted down the aisle by Sharon and Neil Bush, her mother and father, who are divorced. The senior cantor of Manhattan's Central Synagogue conducted the outdoor service, which was followed by a reception in a nearby barn featuring country music, dancing and dinner.

The service reportedly was a case of black tie meeting Western chic, with many of the guests decked out in boots and turquoise jewelry. Among the 200 plus guests were former President George W. Bush, his wife Laura and their daughters Jenna and Barbara; and Uncle Jeb Bush, the former governor of Florida.

The Washington Post reported that Grandma and Grandpa Bush (George H.W. and Barbara) were unable to attend and sent a video message that was played at the Saturday evening rehearsal dinner. Also in attendance were Ivanka Trump, Prince Dimitri of Yugoslavia and Ann Hearst McInerney.

Langenberg grew up here and attended Mary Institute through eighth grade. She went to high school at St. Timothy's, a girl's boarding school in Maryland. She has lived most of her adult life in New York City, where she is active in a variety of charitable and social organizations.

Her sister, Joan Filley Langenberg, and brother, Harry Hill Langenberg, live in the St. Louis area.
