Thomas comes from the Aramaic word for "twin" and was the name of the apostle who doubted the resurrection until he saw Jesus for himself. Thomas Jefferson, Thomas Edison and Thomas Paine are among the many Americans who carried it. The name ranked number 33 in the United States in 2000, drifted down to around number 50 and has been quietly climbing again, from number 51 in 2015 to number 34 among boys in 2025.
