Sorry Pete, I only have information on Nicolas Lacour, and that Antoine de la Cour is listed as his father on the marriage certificate and Francoise (Jeanne?) Duclos as his mother. That is the extent of my information so far. I have just started to look into the LaCour's in France. Concerning your second question, I have not been successful in tracing any LaCour's in France. I do not know if Louis LaCour is related in any to Nicolas LaCour.
