Caroline Bouvier Kennedy, 28, only daughter of the late President John F. Kennedy and Jacqueline Kennedy Onassis, married Manhattan artist and designer Edwin Schlossberg, 41, this afternoon at a tiny country church here, while about 1,000 spectators waited under cloudy skies for a glimpse of the couple.

They emerged shortly before 4 p.m., smiling, after the 30-minute Roman Catholic ceremony which included the singing of "America the Beautiful."

Kennedy smiled demurely and waved her bridal bouquet of white orchids. There was a slight pause before her husband leaned over and kissed her, to the delight of the crowd.

They were taken in a silver limousine to the Kennedy compound in nearby Hyannisport for a reception and wedding supper, attended by more than 400 family members and friends.

Kennedy was given away by her uncle, Sen. Edward M. Kennedy (D-Mass.). Her brother, John F. Kennedy Jr., 25, who drew excited squeals from female spectators, was best man.

But the crowd reserved its most vocal reception for the mother of the bride, Jacqueline Onassis, who emerged from the shingled Our Lady of Victory church on the arm of the senator. She was weeping softly. For a second, she seemed to rest her head on her brother-in-law's shoulder. "CBS Morning News" anchor Maria Shriver, cousin of the bride, served as matron of honor and her husband of three months, actor Arnold Schwarzenegger, grinned at the cheering crowd, stopping for several minutes to speak to Joan Kennedy, former wife of the senator.

The ceremony went off smoothly, and the guests -- including author George Plimpton; former ambassador John Kenneth Galbraith; humorist Art Buchwald; former Connecticut senator Abraham A. Ribicoff; former presidential speechwriters Theodore Sorensen and Richard Goodwin; Onassis' sister, Lee Radziwill, and stepsister, Nina Straight; Straight's husband, Michael, and singer Carly Simon (who arrived 20 minutes late) -- laughed and applauded when the bride and groom shook hands after their vows.

The event was marred slightly when Mae Schlossberg, mother of the groom, tripped and fell on the church step after the ceremony. Apparently uninjured, she was helped to her feet by her husband, Alfred, a textile magnate from New York and Palm Beach.

Police kept the crowd behind ropes, but many climbed trees for a better view. Some had camped out since dawn, waiting for the 3 p.m. ceremony, which started 20 minutes late to the strains of Handel's "Water Music" by The Empire Brass Quintet.

Readings were given by several of the bride's cousins, and bridesmaids included Sidney Lawford McKelvy and Courtney Kennedy Ruhe.

The bride's white silk organza dress (size 4), designed by Carolina Herrera, featured a tight bodice appliqued with embroidered cloverleafs. The long tulle veil was held in place with small satin flowers.
