Where Ilona is most common

Compared with all babies born in each state since 1910, Ilona has been most common in New York (4.2×), New Jersey (3.5×), and California (2.2×), and least common in Michigan (0.81×).

1,104 births recorded by state, 1910–2025. 2× means twice as common as nationally. States with fewer than 30 such births are left blank, and SSA withholds any year with fewer than 5 in a state, so small states read low.
