Rees

Rees is an English spelling of the Welsh name Rhys, which is traditionally connected with ardour or enthusiasm. It is also a Welsh surname, often developed from the earlier personal name. A family may therefore arrive at Rees through either a first-name tradition or an inherited surname connection.

The spelling makes the usual sound more immediately apparent to many English readers than Rhys does. That practical difference does not remove its Welsh background. Reese is another related form, with an additional final e. Rees keeps the name especially compact at four letters and one syllable. For parents considering an ancestral surname as a first name, its history as a personal name as well can give it a particularly natural fit.
