Elva is a multicultural choice, being both an anglicization of the Irish Ailbhe and an feminine form of the name Alf, meaning "elf". Popular in the US at the beginning of the 20th century, it remained in the charts until the 1970s before falling out of favor.

The disgraced heroine of The Scarlet Letter's name, after long neglect, just might have a chance at revival, following in the wake of sister-name Esther. We've characterized her elsewhere as an eccentric aristocrat, much more accepted in the U.K. than she has been here.

Catharina is a feminine name with deep European roots, particularly common in Germanic, Scandinavian, and Dutch-speaking regions. It derives from the Greek name Aikaterine, later Latinized to Catharina, meaning 'pure.' This elegant, classical variation of Catherine carries a regal quality, having been borne by numerous European queens and noblewomen throughout history. While Catherine and Katherine are more common in English-speaking countries, Catharina maintains popularity in continental Europe. The name offers a formal, sophisticated alternative with international appeal. Its rich historical connections and melodious pronunciation give it an air of timeless elegance. Though less common in contemporary America and Britain, Catharina represents a distinguished heritage choice with cross-cultural versatility.
