The Baseball Family TreE

Major League Baseball Brothers, Fathers & Sons, and Other Family Related Research

There are more than three-hundred fifty sets of brothers who have made it to the Major Leagues. More than twenty-five members of the National Baseball Hall of Fame had a brother who also played in the big leagues. Other interesting combos include World Series Appearances, All-Star games, and pitcher vs catcher match-ups.

Add another hundred plus father-and-son combinations, plus a few grandfathers with grandsons, some family teammates, and even a few twins, and you can see that leaves from a tree don't often fall far from the trunk in the Baseball Almanac Family Tree.

"It was brother versus brother in the seventh when Joe Sewell made a whale of a stop and throw to cut down Luke ." - Shirley Povich in The Washington Post (1933)

From 1876 through 2000, only one father-and-son combination played together on the same team ! During the 2001 season the second set played together and Baseball Almanac has both sets in our teammates section.

The rarest familial branch on the baseball family tree belongs to great grandfathers who had great grandsons that each played in the majors. So rare, we included those sets in the fast facts section of our Grandfathers & Grandsons Who Played Major League Baseball .

Did you know that each Major League Baseball family research set listed above has some family related records in the Fast Facts section at the bottom?
