MUSKEGON, Mich. — Postal officials are searching for the relatives of a western Michigan couple who were the intended recipients of a World War II-era letter that was mailed, but perhaps never delivered, nearly 70 years ago.

The Muskegon Chronicle reports ( ) Wednesday that the letter bears an Army Post Office postmark from 1945 and is addressed to "Mr. and Mrs. Sensabaugh" on Washington Avenue, Muskegon.

The sender's name is Sgt. Myron C. Cook, based in New York.

Postmaster William Rowe says it appears someone in Minnesota recently mailed the letter again. A 2013 postmark from Minneapolis was stamped over the original postmark. The letter also appears to have never been opened.

Historian Richard Mullally documents Muskegon County World War II veterans and plans to research the names in the hunt for relatives.
