Madame Montour was the mother of three children. A son, Louis, served as a translator during the French and Indian War. He was killed during the war. Her daughter, Margaret, later to be known as "French Margaret" went on to become the leader of "French Margaret's Town" an Indian settlement at the mouth of Lycoming Creek just a few miles up the West Branch Susquehanna River from Madame Montour's village. Her son, Andrew, took over leadership of Otstonwakin upon her death in the late 1740s. Andrew inherited his mother's gift for languages. He spoke French, English, Lenape, Shawnee, and the Iroquoian languages. Comfortable with both Native Americans and Europeans, he made a good living as a translator for both settlers and local tribes. In 1742 when Count Zinzendorf met Montour, he wrote that Montour looked "decidedly European, and had his face not been encircled with a broad band of paint we would have thought he was one." He also served as a translator with Conrad Weiser and Chief Shikellamy. He was granted of land by the Province of Pennsylvania in the Montoursville area. He was later appointed as a captain in George Washington's army at Fort Necessity during the French and Indian War. Andrew Montour left Montoursville at some point and moved to Juniata County before finally settling on Muntour's Island in the Allegheny River near Pittsburgh.
