What were the names of Horatio children?

Please provide more context. Who is Horatio? Are you referring to a specific character or historical figure?

For example:

* Horatio Nelson: The British naval hero had a son named Horatio Nelson Thompson.

* Horatio Alger Jr.: The American author did not have any children.

* Hamlet's Horatio: The character from Shakespeare's play doesn't have a family mentioned in the text.

Once you clarify who you're asking about, I can help you find the names of their children.
