No idea, but it looks like "S. Hume" to me.
I can't help thinking it has been copied in impressionist style from a renaissance "holy family" painting and that I've seen the composition before. Raphael, or one of his contemporaries?
So like maybe also Leonardo, Michelangelo, or Donatello? Unless maybe I'm off base and you weren't referring to the Ninja Turtles.
I agree that the name appears to be S. Hume.

Can anyone help find any information on this artist
It was found in Ohio if that helps
And has a nailed canvas not staples so probably has some age
I looked in British artists 1880-1940. There are 6 Hume artists, but they are Edith, J. Henry, Miss K.M., Robert, Thomas, Lady Hume-Williams. Their painting genres are comparable to this scene, but that first initial of S. ( if S.) negates these. Gary
