I have been searching for a couple of names, is it possible you can help me?

In my tree Andre L'Esperance and Balzamine Falcon have a child named Marguarite (?) that marries Jean Marie Boucher in June 1902

At the same time Isadore Boucher and Charlotte Plante have Jean Marie Boucher .( was Balzamine and Isadore married at one time as well ? And who are Charlottes people ?)

Jean Marie and Marguarite have a son named ? Athanase or Atharde (Lesperance) Boucher who is born March 1903 in St. Daniel Mb.

He marries a woman named Eva Marie Lilley the daughter of Michael Lilley and Margret Pruden(?)Cooke?

Atharde/Athananse and Eva Marie are my grandparents and I can find absolutely nothing on them.

Do you have any information on any of these people and could you please share ?

Thanks in advance.
