Word was received here on Saturday stating that Captain Theron Woolverton, of the United States Merchant Marine, son of Mr. and Mrs. Frank Woolverton, of Grimsby and New York City, is missing at sea following the sinking of his ship by enemy torpedo. Thirty-two years of age, Captain Woolverton is said to have been the youngest captain in the U.S.-M.M. He joined the service when 17. He was well known in Grimsby, having spent the summer months with his parents here over a period of years. Since the outbreak of war, however, he has been at sea and has taken his ship to many parts of the world with supplies for the United Nations. His parents are in New York at present.
