Dear Wendy: Greetings from South America! My grand-grandfather, Pablo Gasson Venpierre, came from France to Venezuela at the beginning of the past century. They are some 15 Gassons alive in this country, mainly in Caracas.As far as I know, we are the only branch of that surname in South America. I hope that this information may be interesting to you. Sincerely, Rafael Gasson.
