Thank you for taking the time to reply. Unfortunately,I don't know the first name of the person I am looking for. My great grandfather had four brothers who all moved to the U.S. and it could have been any one of them who worked on the canal. I only found out about that recently when I asked my aunts what my uncle had donated to the museum. They said it was the Panama hat that their uncle had worn while working on the canal. They didn't know who he was,though and the uncle is dead who gave it to the museum is dead.
