I am searching for additional documentation concerning my Uncle Patrick Rowan, a U.S. citizen, who was a school teacher for the United Fruit Company in Puerto Barrios, Guatemala 1912-1930. I have photos from the Baker Library, Cambridge, MA. indicating his presence there, as well as a passenger record from the U.S. Ellis, May 13, 1912, Puerto Barrios to New Orleans, LA. I will appreciate any and all assistance. Thank you.
