Where Brennen is most common

Compared with all babies born in each state since 1910, Brennen has been most common in Utah (3.1×), Louisiana (2.6×), and Washington (2×), and least common in New York (0.39×).

6,682 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.
