Tomos is explicitly listed as the Welsh given-name counterpart of Thomas. The Thomas etymology identifies the Aramaic twin nickname behind that family, transmitted through Greek and Latin. This ancestral word meaning does not imply that a modern child is a twin.
Origin
Welsh form of the Aramaic-linked Thomas name family.
The exact Welsh entry identifies Tomos as a male given name; the Thomas entry explicitly lists it as the Welsh given-name counterpart. Thomas traces the name through Greek and Latin to an Aramaic twin nickname. Welsh usage and deeper ancestry are distinguished.
