Hello Magali Felix Garescher, late husband of Marie-Therese Thomas was my uncle and also my godfather. Are you related to Raymond Thomas whom I knew very well in Quebec. I suggest that you join the Association de Généalogie d'Haiti (www.agh.qc.ca)and help complete the data on your family already in the Collective Genealogy of Haitian Families by sending the information to the email address indicated. There are 95 Thomas in the database.
This is one of the best source of data and contacts if you intend to progress further on your genealogical search. You can email me to pursue further
