Early life
T'Hil was born as Morgan Bay on Betazed, she was raised mostly by her father due to her mother and older brother being away on historical research. Morgan traveled often with the crew of the USS Illusion as a youth, as a result she was able to spend time on Romulus with Illusion's Romulan crewmembers. After several visits to the Romulan homeworld, some of the crew, both Romulan and Starfleet, gave the name "T'Hil" to Morgan. The name stuck and she has carried it since.
