With today marking President’s Day and the celebration of George Washington’s birth, alongside the achievements of all 44 U.S. presidents, we thought it only right to draw up a little history lesson that just so happens to touch on one of our favorite topics: baby names. Yep. We combed the web to bring you this list of presidential offspring. While compiling the roundup, we weren’t only shocked to see just how many kids some of our early presidents fathered, but also saddened to see how many children didn’t make it through birth, infanthood, and childhood. Not to mention, the fuzzy math on just how many “illegitimate” children, some born to slaves, have been poorly accounted for. On a more cheerful note, there’s some fascinating stuff below—from shifting family sizes to trends in monikers (and nicknames). Have at it!
