Tyjaun is of African-American origin, derived from the Swahili word 'tujana', meaning 'let's meet'. It gained popularity in the United States during the late 20th century, often used as a unisex name but more commonly given to males.
"Tyjaun saw a surge in births between 2001 and 2005, with eight babies welcomed in the latter year compared to six in 2001, making for a total of fourteen Tyjauns born during this period."
