I have no idea of the family names that you are trying to find in Brazil but am interested in your James name. Are your James family also from that area of Indiana? My husbands great grandmother was an Emma Helen James and we cannot find her parents names so far. Story is that they are related to the infamous Jesse James. Are you also? Our Emma Helen was married and died in Vermilion County which is next to Clay County in Indiana. Thanks for your time. Kaye
