I know this is an exceedingly old thread, but I'm looking for some more info on the parents of Arsina. I'm the great great great grandson of Arsina's sister, Marie Mercier, who was born while the family lived in Fall River, Mass in 1867. I'm looking for any info on The parents of Arsina and Marie. I have names an approximate dates of birth for Philomene Janson/Genson and Francois Xavier Mercier, but no leads on potential parents for either. I have an idea for Philomene's parents but not proven. Any help is appreciated. Thanks all!
