The Baseball Family Tree

There are more than three-hundred fifty sets of brothers who have made it to the Major Leagues. 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)

Through baseball history 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.
There is only one great grandfather and great grandson combination ever in Major League history - and it is not the commonly cited Boone family.
Did you know that each section listed above has some family related records in each of the Fast Facts sections?
