Last year (2022) there were 118 women in Poland with the first name Elsa. Interestingly, not enough baby girls were named Elsa in 2021 to make it into the baby name ranking. In a way it makes sense, given that Elsa is not a standard Polish name, it's either the full Elżbieta or Elza, the latter being quite rarely used, but given that many a lot less obviously Polish names are given to Polish children, as well as the popularity of Frozen and how easy Elsa is to pronounce and spell, it's kind of weird that there aren't more baby Elsas here.

Elsa is also Estonian, used as a short form of Eliisabet. The name day for Elsa in Estonia is November 19.

In January 2020, 140 women in Poland had the name Elsa as a first name. 55 had it as a middle name. Quite surprisingly (at least to me, given the popularity of Frozen and the internationality of the name, it doesn't figure in the Polish most popular baby names ranking for 2019 at all, and the more familiar form Elza was also hardly used).

The Polish form of this name is Elza, but, curiously, last year (2018) there were 4 little Elsas born, placing this name #461 in the ranking for girls, but Elza was not ranked.

Apparently also occasionally used in the Czech Republic: https://krestnijmeno.prijmeni.cz/search.php?name=Elsa&t=1

Most probably due to the overwhelming popularity of "Frozen", the name Elsa itself is gaining some little popularity in Poland as well. It's not much, because even the native Polish variant, Elza, is not (and from what I know has never been) particularly popular, neither as a full name nor a nickname, but still, last year (2017) there were 3 little Elsas born, as well as for Elzas. Elsa was on 511 place in the ranking.

Just wanted to tell you that it is also a Faroese name and that it is quite common in the Faroe Islands.

Also Greek.

The name is also used in Iceland. [noted -ed]

To end the speculation of whether or not Frozen increased the usage of this name, it did. It jumped 241 positions from 2013 to 2014.

Elsa is also a fairly common name in Ethiopia and Eritrea.

Elsa is also used in Portuguese.
