Tad photo?

[AussieMick]

If the image is circa 1862 then Tad would be 9. I think the boy is younger. ... maybe 6 or 7. The one on the right looks older.
My thinking was Tad was photographed twice . .... maybe 1861.... in the photographer 's standard costume and later in the gifted one .... yes, all guesses on my part. The one the right is c. 1864 according to Wikipedia which puts Tad at 11 years old .... much older than the Left image.
