In the Michigan Pioneer and Historical Society, vol. 29, pp. 42-3, the following information is given in an obituary notice for Ann Basset Fall published in 1898:
Following their marriage, Benjamin and Ann "very soon moved to Canada... In the exciting and rebellious times through which Canada passed about 1837, Mr. Fall's intense patriotism to the land of his birth and his antipathy to the English oligarchy became so pronounced that they were obliged to abandon all their possessions, allow their property to be confiscated, and fly for safety to the United States. Their flight was by a log canoe down the river Thames and across Lake St. Clair."
Benjamin passed through Michigan to Indiana, where he cleared a farm in Noble County and where at least one of his children - Charles Stuart Fall - was born, in 1840. Not being satisfied with the local schools, however, he moved his family to the vicinity of Ann Arbor.
During these years, tragedy struck Benjamin's family. An epidemic of scarlet fever took the lives of his four daughters, Esther, Ellen, Mary, and Alice. Somehow the family recovered from the blow, the birth of twins in 1848 perhapes helping to set them looking foward again.
One account states that Benjamin was a blacksmith, though there is no evidence in Charle's letters home from the Civil War, which refer only to farming activities. Though the 1850 census lists him as a Blacksmith.
After living in Hamburg, Michigan during the civil war years, Benjamin moved into Ann Arbor itself, "where he was a member of theMethodist Episcopal Church and held many official positions in... the denomination. He was also prominently identified with the Masonic lodge."
