Trelisa is a unique and distinctive given name, deriving from Welsh origins. It is composed of two elements: 'tref' meaning 'town', and 'llysa' which signifies 'happiness'. The name Trelisa thus translates to 'happy town', suggesting a place of joy and contentment.
The name Trelisa was given to five newborns in 1992, making it relatively uncommon even within that year.
