From Baseball Almanac
The"modern" (since 1900) National League record for home runs allowed in a game is six and it has been allowed three times by three different pitchers: Larry Benton of New York on May 12, 1930, Sloppy Thurston of Brooklyn on August 13, 1932 & Bill Kerksieck of Philadelphia on August 13, 1939.
Some entire pitching staffs are infamous and get their own team related home runs allowed records which we have posted below:

Did you know that only two pitchers in Major League history have ever given up four consecutive home runs in an inning? On July 31, 1963, Paul Foytack of the Los Angeles Angels set the mark and forty-four years later Chase Wright, on April 22, 2007, tied the record.
