I have found on the internet that the father of Paul Augustin la Pellitier de la Houssaye, was Nicholas la Pellitier de la Houssaye from the Kingdom of France, and the father of Nicolas was another Nicolas la Pellitier de la Houssaye, and they were residing in the Kingdom of France. I know that there is a place named Delahoussaye, which is not too far from Paris, France.
I am not a Delahoussaye descendant, but I am also a researcher and consider myself a very good friend of the family.
We share a mutual Delahoussaye friend, Mary or Dee originally from the Franklin way and now the Lafayette way.
