    The idea behind the subquery is that it separately gets the latest (maximum) mod_Date for each name. The result of which is then joined back to the original table to get other columns in each row.

    SELECT  a.*
FROM    tableName a
        INNER JOIN
        (
            SELECT name, MAX(mod_date) maxDate
            FROM tableName
            GROUP BY name
        ) s ON  a.name = s.name AND
                a.mod_date = s.maxDate
