Meaning and history
Keitha is a modern English feminine form of Keith. Keith began as a Scottish surname derived from a place name, probably containing a Brittonic or Gaelic element associated with woodland, though its exact etymology is uncertain. The feminine ending -a was added in modern naming practice and does not create a separate ancient meaning. The name is uncommon, and reliable prominent bearers are limited; Australian historian and author Keitha Dunstan is one documented example.
