It is an older western movie were there are 5 or 6 bandits who come and kill an entire family except for a little boy who one of the bandits hides under a table(but the boy still sees his entire family killed and rembers how all the bandits had different tatoos) then trains for the rest of his life so he can kill them, bit he kills all of them except the one who had put him under the table and saved him

Here's a possibility:

Kid Vengeance aka Vengeance (1977)

I'll see what else I can find in this category.

I am trying to find this for my dad and he said that there is no sister and he was all by himself

I'll keep thinking! Sometimes it's a matter of narrowing it down.
