Cecila was born under the name of Cecilia Amore to unidentified parents. It is incredibly likely that she grew up in Pleasantview as she met her husband Alexander when they were teenagers. She seems to have had dreams of working in the Entertainment business since childhood or at the very least since her teenage years.
After becoming an adult, Cecilia married her teenage sweetheart Alexander and moved with him to a mansion in Moon Islands. She found a career in Entertainment as a lounge singer, a job she truly enjoys. At some point, both she and Alexander successfully used the Elixir of Life, making them a bit younger.
