I'll bet that one of your ships was the HENRY D. WHITON rather than HENRY D. WHITTEN.
The SS HENRY D. WHITON was built by Newburgh Shipyards, Inc., Newburgh, New York, completed in May 1921. She was renamed the AMABILITAS in 1946, then became the ARCOBALENA in 1951. She was scrapped in 1959. See http://www.shipbuildinghistory.com/history/shipyards/4emergency/wwone/newburgh.htm and scroll down to Hull #19.
A merchant marine radioman has posted his recollections of sailing in the HENRY D. WHITON, probably in 1944, at http://www.soldiersmuseum.com/pages/usms/spark_gap/1999_autumn.htm; scroll down to "Wartime Voyage Number Six."
Henry D. Whiton, after whom the ship was named, was the president of Union Sulphur Company, the company that owned and operated the ship.
