One of those short, punchy names with its roots in a variety of different cultures and languages, Rina is sister to names like Mina, Mira, Lina, and Nina. Retro in feel, but never overused in the US, it peaked in 1980 when it was given to 90 girls.

Like many short forms now popular as full names in the Netherlands, Coen—also spelled Koen—originated as the diminutive of the more old-fashioned Coenraad, the Dutch Conrad. In this case, it would be pronounced as KOON, with a short oo sound.
Alternatively, it may be used in the US as a variation of Cohen, which stems from the Jewish surname designating a priest, and thus pronounced as CO-uhn. Additionally, it may also relate to the Irish surname McCown ("of Connacht") or to the Australian place name, Coen, meaning "thunder" from its Indigenous roots.

This Americanized spelling of the Dutch name is now used nearly exclusively for girls in the US.

Malena is a feminine name with multiple cultural origins. In Spanish, it's often used as a diminutive of Magdalena, deriving from Mary Magdalene in the New Testament. In Greek contexts, it relates to meanings of 'light' or 'bright.' The name has gained popularity in Latin American countries and is increasingly recognized internationally. Malena has a melodic quality that contributes to its appeal, with three flowing syllables that give it a gentle rhythm. The actress Malena Alterio and the film 'Malena' starring Monica Bellucci have added to the name's cultural visibility. The name offers a balance of familiarity and distinctiveness, making it accessible while still feeling somewhat uncommon in many Western countries.

Holland, like most place names, is intrinsically gender neutral, but in practice today it's mostly female. There's about one boy Holland born in the US these days for every five girl Hollands. That's a reversal of the last century, when Holland peaked as a boys' name in 1893, falling off the Top 1000 completely in 1913.

The name of Rip Van Winkle – and Rip (born Elmore) Torn – will probably never be ready for further consumption, if only because of the implications of R. I. P. The only thing that could save it is Rip Wheeler, the handsome ranch foreman on the soapy Western Yellowstone.

Fenne and its phonetic version Fenna are vintage names enjoying a resurgence in The Netherlands, where both make the girls' Top 100.

The short, cute Pim is a Top 100 boys' name in The Netherlands though little-known outside that country. But in a family overrun with Williams, Pim could make an original nickname setting a modern child apart from father Will and grandpa Bill.

Sanne is hugely popular in the Netherlands, but almost unknown here; which makes it an interesting prospect for the parent in search of an unusual name. Pronounced sah-na, Sanne is in keeping with the Dutch taste for nicknames plucked from the middle or end of a name vs. the beginning, such as Bas for Sebastien or Bram for Abram.

Yes, though it seems so extreme, girls were actually sometimes given this name a century ago; now it is so uncommon it would make a strong springtime statement. Biggest obstacle: the nickname Daffy.
