Hi Becky,
The only Piquette I really know about is Joseph Picquette (he was Pickett in his obituary), who was my grandmother's maternal grandfather. I do know that they were French Canadian but there are so many people with the same name that I'm just trying to narrow things down based on birth dates/locations, etc. I actually saw his obituary card as a child, but unfortunately, my grandmother destroyed a lot of family pictures and things when her Alzheimer's got bad, and that was one thing that was lost, so I ahve to guess on date of birth. I know that his daughter settled in Northern Minnesota, where I'm from originally, but it looks like she was born in southern/central Minnesota, so they may have migrated from another area before moving north. I will definitely keep you posted if I find some more information.
