USS Lichfield
From Star Trek: Theurgy Wiki
The USS Lichfield was a 24th century Federation starship operated by Starfleet.
In 2355, the chief engineer of the Lichfield was Anna Williams, wife of Jack Williams and mother of Rhys Williams.
(So far the class of the USS Lichfield has not been revealed nor is it clear if it is still in service in 2381. If Anna Williams was a lieutenant when she held the position of chief engineer the USS Lichfield would be a small ship such as an Oberth class. If Anna Williams had the rank of lieutenant commander back in 2355, she could have been the chief engineer to almost any starship in service and was likely a commanding officer with the rank of captain by the time she perished in the Battle of Wolf 359.)
