Question: a man has no name jaqen h'ghar?
Answer: "Jaqen H'ghar" is just a persona adopted by one of the Faceless Men of Braavos, but the Faceless Men have no personal names. While as "Jaqen H'ghar" he claimed to be from Lorath, this was just part of his fake identity, and and there is no indication that he has ever even set foot in Lorath.
