My husband's great grandmother Marie Hortense Tuaillon b. about 1862 was married in US about 1880 to Walter Achey in either California or Missouri. It seems that most people of the Tuaillon surname lived in Haute Saone and Vosges at the time she left France. We know nothing about her family. Can anyone tell me why someone/families might have left in this period? Did many people leave this area in the aftermath of the Franco-Prussian War?
