abigailcrawford4's list "Future Daughter" of 2 great name ideas: Elsa - Mathilda!

Future Daughter

Lost in limbo for decades and decades, Elsa now stands a good chance of following along in the progression from Emma to Ella to Etta, thanks to the ice queen heroine who "Let It Go" in the wildly popular Disney movie Frozen. The name shot all the up to Number 286 (its highest ranking since the 1890s) in the year after the release of the movie, though it's now dropped back down the list in the US.

Elsa has international credibility, ranking in the Top 100 in countries as diverse as Sweden, Spain, and France. If Elsa, is just too Frozen for you, sister name Elsie is also on the rise, especially popular in English-speaking countries.
 Elsa came into English-speaking use in the nineteenth century, boosted by Wagner's operatic bride in Lohengrin&mdash;the first to walk down the aisle to the famous wedding march. For a while Elsa took on a leonine image via the lioness in the popular book and movie Born Free, but that's all but forgotten. Elsa has lots of varied and interesting human namesakes, including designer Schiaparelli, writer Morante, Bride of Frankenstein Lanchester (born Elizabeth).

The addition of the h makes it more Old World, which is not the direction you want to push Matilda in.
