DANFS is the Dictionary of American Naval Fighting Ships. It is kept by the Department of the Navy and contains the official summary of the ship's history and information. It should be the first place to look for ship information.
Orvetta is listed in the DANFS as a 'merchant name' with no further details. It was probably the name of an individual in the shipping industry.
The U.S. frigate Constellation was heavily engaged in the undeclared naval war with France 1798-800.http://www.history.navy.mil/danfs/c13/constellation-i.htm

There are three listings for the Randolph including the reunion association. There are histories of the Randolph on the web if you do a search. There is a book called The Gangway-A pictorial history of the U.S.S. Randolph's first year at sea. Oct. 9 1944 to Oct 9 1945. Published by the officers and men of the U.S.S. Randolph. Published 1946. There is also a book called Fighting Squadron Twelve The editors were-Lt. Roy Bruce, Lt. R.E. Monaghan, Lt. H.W. Hewlett and Lt. Geo. Maxwell. This squadron was based on the Randolph. Probably published about the same period. My father served aboard the USS Randolph during WWII. If you forward your e-mail I'd be happy to get his e-mail to you. I know he'd love to talk about his experiences. He recently pulled out the Randolph "yearbook" while we were visiting to show his grandchildren. Please visit my website at ussrandolph.com This is a new website dedicated to the preservation of the history of the USS Randolph CV15.
