Cledis is a unique and distinctive given name of Welsh origin, derived from the personal name Cledwyn, which is composed of elements meaning ' leader' and 'white'. This name has a historical significance in Wales, as it was borne by Cledwyn ap Cadwallon, a 6th-century king of Gwynedd. The name Cledis is often associated with strength, leadership, and nobility due to its royal provenance. It is also noteworthy that the variant spelling Cledith is found in some sources, offering an alternative form of this unusual yet appealing name.
The name Cledis was quite popular in the early to mid-20th century, with a notable peak of 10 births in 1931. However, its usage appears to have significantly declined after 1968, as there are no recorded births of this name since then.
