I saw your posting on the Ethier family and was wondering if you had traced the family back. The reason I ask is that I am trying to locate the parents of Francois Laverdure and Sophie Dupuis. The reason I mention my ancestors is that Edward Laverdure was the witness but upon looking up his
marriage, Francois Laverdure was his witness for the marriage of a Eduard Ethier dit Laverdure. In other words, Ethier might have been a two part name name, "Ethier dit Laverdure". The time line does seem to fit as the marriage of the Eduard Ethier dit Laverdure was at the Notre Dame de Ottawa in the 1820's. Just wondering if you had the ancestors of your Eduard Ethier as it might connect to my ancestors.
