Lionel is yet another traditional boy's name entering the girls' column--at least once-- via prizewinning novelist Lionel (born Margaret Ann) Shriver.

Lionel is one leonine name that hasn't taken off as cousins Leo and Leonardo have, though it did reenter the Top 1000 in 2010 after several years away; it was at its highest point in the 1920s and 1930s.
