His great uncle
The father's son is the uncle of the son of the father's daughter.
No because that would be your cousin
Your uncle's son is your first cousin.

It means you have (or had) at least two uncles and at least two great-uncles, and that is all it means.
The usual way this puzzle is stated is... A man is showing a photograph of a man to a friend of his. He says Uncles and brothers have I none, But this man's father is my father's son. Who is the person in the picture? The picture is of his son.
Your brother's daughter's daughter is your great niece.
They are your Uncles and or Aunts.
your uncles son is your cousin
