Dear Diane, thanks for the information. As I said before what I know is that my great grand father arrived from Switzerland to Buenos Aires Argentina, he ran a business later when he moved to Montevideo Uruguay. He was an ingeneer and he worked with something related to heaters. His name was "Roberto" but we still keep the spelling Leemann. I know my great grand father got married at least three times so there are relatives in Argentina too. Let me know what is the information that you need and I'll try to find it. regards, Leslie.
