Child Actors 1960s

For something I am writing I need examples of cute blonde 12 year old boys in movies and shows from the 1960s that many people would recognize.

I once knew a boy who looked sort of like this boy in this painting (but the boy I knew was blonde)

The complete painting can be seen here:

The boy I knew was about shoulder height or five feet tall, blonde, and looked like a 12 year old. His face looked vaguely like the boy in the picture. I think that he was cute enough to be a cute looking child actor, like Ricky Schroeder aged 12, Chad Allen aged 12, David Gallagher aged 12, or Macaulay Culkin aged 12.

But I would like to have more examples from various eras to compare him to for readers of various ages who might not be familiar with the ones I mentioned.
