No etymological entry is currently available for Castle in our reference dataset. These figures derive from SSA's annual national and state-level name files, which include any name appearing at least five times in a given year or state-year; names below that threshold are suppressed for privacy and therefore excluded from the totals shown here. The 367 total represents a lower bound — actual usage may be higher in years or states where the count fell below the disclosure floor.
