History: The North American Indian By Edward S. Curtis

In 1892 Edward married Clara J. Phillips (1874–1932), who was born in Pennsylvania. Her parents were from Canada. Together they had four children: Harold Curtis (1893-?); Elizabeth M. (Beth) Curtis (1896–1973), who married Manford E. Magnuson (1895–1993); Florence Curtis (1899–1987) who married Henry Graybill (1893-?); and Katherine (Billy) Curtis (1909-?).
In 1896 the entire family moved to a new house in Seattle. The household then included Edward's mother, Ellen Sheriff; Edward's sister, Eva Curtis; Edward's brother, Asahel Curtis; Clara's sisters, Susie and Nellie Phillips; and Nellie's son, William.
