The story of Tj

TJ is a name made from two initials. It started as a nickname for boys whose first and middle names begin with T and J, such as Thomas James, and some families now register it on its own. There is no single meaning behind it; it stands for whatever names the family has in mind, or simply for itself.

TJ first appears in the CSO records in 2003, and for many years it was given to only a few boys a year.

Like AJ and JJ, it has grown in the 2020s. Its best year was 2024, with 11 boys and a place at number 339 once the spellings are combined. The CSO records each way of writing it separately: Tj had 10 boys in 2025, while T.J. and T J appear in some earlier years.
