Lord was presumed dead and his name was added to the Tablets of the Missing at the American Cemetery in Florence, Italy, where more than 4,000 members of the American service are buried.
He remained missing until last year when divers saw the wreckage of his plane and his remains at the bottom of the sea.
A native of Conneaut, Ohio, Lord was returned to his family on Saturday when his remains were flown to Cleveland. His coffin was draped with an American flag and escorted by police to the Marcy funeral home of his hometown.
Of the 16 million Americans who served in the Second World War, more than 72,000 are still missing, according to the US Air Force press release. Among the missing are 24 members of the 57th group of hunters, to which belonged Lord.
