It is also the name of a family from the island of Chios who settled in Britain in the early 19th century. Prominent members included the art collectors Constantine Alexander Ionides, son, and Alexander Constantine Ionides, father.
The Ionides dwelt at Elis, where they had a sanctuary near a spring flowing into River Cytherus, and were said to have the power to cure various diseases. Their surname was thought to have come from the name of Ion, son of Gargettus.
