While Tessa is now preferred, this slightly sharper diminutive of Theresa was the more familiar option in the early 20th-century. It enjoyed a brief return to the US charts in the 60s and 70s but is currently given only to a handful of girls each year.

Aleph came into the spotlight when chosen by Israel-born Natalie Portman for her son. Alef is a more common spelling of these related Hebrew baby names.

In the days of huge families, this name of the Roman goddess of prophecy and childbirth, and one of the Fates, would be saved for bambina number ten. Now it might be used for a girl born in October, the tenth month.

Never as well known as that other Roman numeral name, Octavius, Tertius just might hold some appeal for the parent seeking a really obscure name with the patina of antiquity for her third son.

Octave shortens Octavius to a more manageable length, keeping the "eighth" meaning. In English speaking countries, however, people could easily confuse this with the musical and poetrry term octave.
