they are related. the NY Times ran a special on Lamont a couple weekends ago.
Mr. Lamont grew up in Syosset, N.Y., in a family that had long been
involved in business and usually voted Republican; a
great-grandfather, Thomas Lamont, was a chairman of J. P. Morgan,
though a great-uncle, Corliss Lamont, was a well-known socialist.
Mr. Lamont attended Phillips Exeter Academy, Harvard, and the Yale
school of management before moving to Greenwich. He and his wife,
Annie, have three teenage children, two girls and a boy.
