Everything old new again

With its relation to Mount Olympus, home of the Greek gods, and to the Olympic games, this name has an athletic, goddess-like aura, making it the perfect Olivia substitute.

A sweet, nostalgic nosegay kind of name, Posy has been long fashionable in England, a country of gardeners, but this pretty bouquet-of-flowers name is still rarely heard in the US, though it could be seen as a more unusual possible alternative to Rosy or Josie.

Sweet and cosy but with substance too, Sosie is a rare, multicultural name. Used as a short form of Susan, Sosan, Sophie and Sophia, it could make a fresh alternative to Suzy, Izzy, or Josie; alternatively, it's an Armenian name in its own right, derived from Sosi meaning "palm tree".

Heloise is an ancient name related to sleek, peppy classic Eloise. Both ultimately derive from the Germanic name Helewidis, which became Helewis in medieval England. In the twelfth century, the name was borne by the beloved of the French philosopher Pierre Abelard, who was considered to be one of the most learned women of the Middle Ages.

A name that seems to be a combination of Isabel and Susannah, used in the United States in the 18th and 19th centuries, most notably for a daughter of Paul Revere. Isannah was also a character in the 1943 Revolutionary War novel Johnny Tremain. An unusual old choice with modern possibilities.
