Teshawn is of African origin, derived from the Swahili word "tesha" meaning 'thank you'. It gained popularity as a variant spelling of Dashawn, which was created by adding the prefix 'Te-' to Shawn. The name Teshawn first appeared in the U.S. baby name rankings in 1997 and has since maintained a steady presence, though it remains relatively rare.
"Teshawn saw a consistent number of babies named each year from 1976 to 1986, with an increase to six in 1990. Altogether, 26 children were given the name Teshawn during this period."
