CONCORD, N.H., April 29 (Reuters) - New Hampshire’s Senate passed a bill on Wednesday that would legalize same-sex marriage after an amendment was added that prohibits polygamy and marriage of family members, among other measures.

Governor John Lynch has not indicated if he will veto the bill, which passed the Senate by a vote of 13-11 and would make New Hampshire the fifth state in the nation where gay marriage is legal. But the Democrat has expressed opposition to it. It has already passed the state’s House of Representatives.
