From the name of the city of Kimberley in South Africa, which was named after Lord Kimberley (1826-1902), whose surname meant “CYNEBURGA’s field” in Old English. The city came to prominence in the late 19th century during the Boer War. Kimberly has been used as a given name since the mid-20th century, eventually becoming very popular as a feminine name.
From the Greek name Αλεξις (Alexis), which meant “helper” or “defender”, derived from Greek αλεξω (alexo) “to defend, to help”. This was the name of a 3rd-century BC Greek comic poet, and also of several saints. It is used somewhat interchangably with the related name Αλεξιος or Alexius, borne by five Byzantine emperors. In the English-speaking world it is more commonly used as a feminine name.
