Thomas

Thomas is also a common Cornish, Welsh, German [noted -ed], Dutch, Danish (used alongside Thomassen in Denmark), and Greek surname, derived from the given name Thomas. In fact, Thomas is currently the 95th most common surname in Germany. Thomas is also used by Indian Christians as a surname, mostly by Saint Thomas or Assyrian/Syriac Christians in the state of Kerala in the south. This is perhaps due to Saint Thomas the Apostle, who is believed to have spread Christianity to India.

It's also used by Indian Christians, mostly by Saint Thomas or Syriac Christians in the state of Kerala in the south (written as "തോമസ്" in Malayalam). This is perhaps due to Saint Thomas the Apostle, who is believed to have spread Christianity to India.

I think it is also a Greek surname (rare surname).
