The geographical weirdness: left-handedness is much more widespread in Northeast, with some less prominent peaks in Florida, Arizona, South Dakota. The source is suggested to be genetic.

I wonder if there's information on how many passengers of the Mayflower were left-handed.

Probably 0% reported, considering the negative views towards left-handedness at the time.

My son is left handed. Nobody else in my or my wife’s family is or has been left handed, that we know of. And we don’t live in one of the mentioned areas. It seems odd, but I’ve never looked into it.

I’m the same. No one in my family tree going back to my great grandparents were lefties. Nor any cousins or 2nd cousins. Just me.

Me and my sister are left-handed, but nobody else in our family. And suddenly not one but two kids? (We're not twins.)

That is… bizarre indeed.
