This truly is a Kennedy-family wedding year. Almost overlooked in the glittery media events that the upcoming weddings of Maria Shriver to Arnold Schwarzenegger and Caroline Kennedy to Edwin Schlossberg are certain to be is the Washington wedding of Timothy Shriver and Linda Potter. Maria's 26-year-old younger brother will be married at the Dahlgren Chapel on the Georgetown University campus on May 31, little more than one month after the Shriver-Schwarzenegger wedding April 26 at Hyannis Port, Mass. This is a busy wedding season for parents Sargent and Eunice Shriver, who have five children and suddenly the first two are being married at almost the same time.

The Shriver-Potter nuptials may not draw the media attention of the other two, but there will be Kennedys everywhere. About 300 to 400 guests are expected and there will be 15 groomsmen and 15 bridesmaids. Timothy will be a groomsman in his sister's wedding and she will be a maid of honor in his. Timothy, a Yale University graduate who is finishing work on a master's degree from Georgetown, works in the New Haven, Conn., public school system with underachieving children from low-income families. Linda, 29, a Georgetown graduate with a law degree from Vanderbilt University, worked for the Washington law firm of Latham Watkins & Hills.

Timothy and Linda will be married in an ecumenical ceremony that will include New York Episcopal Bishop Paul Moore and Fr. Richard Fragomeni, the former director of liturgy for the Diocese of Albany and a doctoral candidate in liturgical studies at Catholic University.
