An energy company says the two Americans on board missing Air France Flight 447 were a geologist and his wife.

Devon Energy Corp. confirmed Tuesday that Michael Harris and his wife, Anne, were on the airliner that disappeared over the Atlantic Ocean on a flight from Brazil to Paris with 228 people on board.

Company spokesman Chip Minty says Michael Harris was a geologist in Devon's Rio de Janeiro office. Harris had moved to Brazil from Houston in July.

Anne Harris' sister, Mary Miley of Lafayette, tells the Louisiana newspaper The Advertiser that Anne Harris was originally from Lafayette and the couple had lived there until 2004. She said they had been married for 16 years.
