Former President William Clinton will arrive on Martha's Vineyard today for a long weekend with his wife, U.S. Sen. Hillary Rodham Clinton (D-N.Y.), and daughter Chelsea.

The family will stay at the Chilmark home of Kenneth H. Iscol, a cellular-telephone industry executive. Mr. Clinton will celebrate his 56th birthday here on Monday.

The Clintons first visited the Island in 1993 and except for 1996 have returned to its shores every year since.

There are plenty of events this weekend for the former president to enjoy, from the 141st annual Martha's Vineyard Agricultural Society Livestock Show and Fair in West Tisbury to the Oak Bluffs fireworks Saturday night.

This is the first year the Clintons will stay outside of Edgartown. During his first visit, he stayed at the home of Robert S. McNamara, former secretary of defense in the Kennedy and Johnson administrations and a longtime seasonal resident of the Vineyard. On subsequent vacations on-Island he was a guest of Richard L. Friedman, a mainland real estate developer.

The Iscol family includes Mr. Iscol's wife, Jill, and their two children, Zachary - a friend of Miss Clinton - and Kiva.

Last year, the Clintons visited the Iscols' summer home overlooking Menemsha Pond for a ceremony honoring Zachary, who joined the U.S. Marines as an officer.

Mr. Clinton will leave the Vineyard Tuesday.
