Curious---Tad left or right handed?

[Angela]

I dont have access to it right now, but would not Julia Tafts diary/book make mention of it if Tad was left handed. She observed the Lincoln children closely and spend a lot of time with them.

@Eva: while the custom of "re training" left handed children in German schools existed, it was not practiced everywhere. I was never asked to use my right hand for writing and neither were any of my cousins or even my mother.

That's interesting. Did you grow up in a Catholic area?

It has always been fairly balanced. However, three of my cousins of which two are left handed, as well as my mother grew up in rather catholic Mainz.

Can one tell if a person is left-handed from their handwriting?

I think it would be difficult today since, depending on how I hold my arm while writing, the letters lean either left or right.
However, I cannot imagine that this was possible in a time when ink would have been smudged heavily when one tried to drag his arm after the written words.
So what I am trying to say is that his letters would either lean left or be straight if he was left handed.
