As far as Leonard Hus-Lemoine is concerned ... I believe that you are correct. When I began my research I saw his name listed as "Leonard Hus-Lemoine" from information that was shared with me online. I believe this was an error of someone from a "Lemoine" branch that mistakenly thought the name was always "Hus-Lemoine". One could make the same mistake by calling him "Leonard Hus-Latraverse, Leonard Hus-Millet or Leonard Hus-Cournoyer".
So I've come to that same conclusion .. and I just wanted to clarify that.
