Dalles is a distinctive and uncommon given name of French origin, meaning 'waves' or 'surf.' It's a unisex name, though it's more frequently used for males. The name Dalles is believed to have evolved from the medieval French word 'dalle,' which refers to large stone slabs used in construction. In some cases, it may also be associated with the French city of Dax-les-Bains, known for its thermal waters.
The name Dalles experienced a decline in popularity from the mid-20th century onwards, with its peak occurring between 1978 and 1998 when five births each year were recorded. It was not until 2013 that there was another notable increase in usage, with six births registered that year. Overall, a total of 33 births bearing the name Dalles have been recorded annually from 1940 to 2013.
