First recorded in the U.S. in 1924, Tam peaked in popularity in 1982, though it has remained relatively rare. Its trajectory shows a rise since 2022, suggesting renewed interest. With a recent rank of 12,008 and a frequency of 1 in 341,615, Tam is an uncommon but recognizable choice. Its versatility across cultures makes it appealing for parents seeking a simple yet meaningful name.
