How this list is chosen
Each name is a different published profile, not a second spelling of Luka or of a name already listed. It matches at least three of: length within one letter, the same last two letters, a peak within 15 years, the same direction from 2021 to 2025, and a 2025 count between one quarter and four times Luka’s larger count. One of the matches is the ending, the peak, or the direction. The table keeps 12 names, at most 12. Sister names are the larger female count, brother names are the larger male count, and an equal count is unisex. A missing earlier count is skipped, not treated as zero. This is not a ranking of which sibling sounds better.
