My ancestors were Marie Macoutenticoue (Native American) b abt 1700, died after 1744, and Pierre Roy b abt 1665 in probably Quebec and died June 1, 1721 in Kaskaskia.They md. abt 1716 in Kaskaskia, IL Territory. Their daughter, Marie Louise Roy, was babtized August 23, 1717 in Kaskaskia, IL. She married abt 1734 to Pierre Lacourse, son of Pierre Gelinas dit Lacourse of Quebec. There must be other descendants out there. Does anyone know about these people?
