Hoping all is well. Sorry for the long delay (years) but I myself had the same problem with my computer and backup, ironically identical to your own experience, and unfortnately never have recovered and lost everything. But I am attempting to piece things together and hopefully restore all I have lost. Fortunately (or maybe not) my Bulrice (Boulerice) family re-union is in two weeks and I have not got even close to making things work. So if I do I will be sure to keep in touch. And regarding the Jean Baptiste LeBourhis, the data I had was just what was listed in the Latter Day Saints Website (FamilySearch.Org) and others and just what was on there is what I had utilized, so if you have more accurate info, please I welcome the opportunity to have all things correct of course!
Hope to hear from you...and e-Mail is: firstname.lastname@example.org
