My Great Grandmother was Melissa Flandreau Bachant Charette. She was the older sister of your Emma Jane Flandreau Logan. Melissa was born in December 1859 and Emma Jane was born in April 1862. My Paternal Grandmother, Clara Emma Charette Mulloy Mellgren, would have been a first cousin to Robert Ray Logan. My father, Samuel Mulloy, would be a second cousin to Beatrice E. Logan and Raymond Logan. My grandmother and my father were born in Passaic, NJ, and are buried in Paterson, NJ, as is Melissa.
I would very much like to exchange any information that I have about the David Flandreau Family. My grandmother had an older half brother named David Flandreau Bachant (1878-1943). I've been in touch with one of his grandsons recently.
