Meaning & origin

Clydia is a rare feminine name that first appeared in U.S. birth records in 1900, the same year as its peak usage. It has never ranked among the top 1000 names and remains an extremely uncommon choice. The name may be a feminine elaboration of Clyde, a Scottish river name, or a creative spelling influenced by names like Lydia. Despite its obscurity, Clydia offers a distinctive alternative for parents seeking an uncommon vintage name with a soft, melodic sound. Its trajectory has been stable, with only occasional recorded births, and no strong regional concentration.

Clydia likely derives from the Scottish river Clyde, used as a given name for both sexes since the 19th century. The feminine form Clydia appears as a rare variant, possibly influenced by names like Lydia. It has no established meaning outside the river name tradition.
