Sophie Grossman is listed as the wife of Adolph Segal in the census.
A Sophie Grossman arrived in 1911, age 16, on the ship Nieuw Amsterdam, manifest line 23 but I am not sure if this is the same Sophie Grossman, as Adolph's arrival is 1902 and he says that his passage was paid by "intended wife" and gave her address as New York, not Romania.
Many Grossman's arrived in the USA in 1902 (the year Adolph arrived) all from Romania. Some list their ethnicity as Romanian/Hebrew and some as Romanian/Hebjarg. Some of the immigrants are: Abraham (37); Amelia (23); Josell (1); Leon (17); Samuel (45); and Ysak (39). Check the website ellisisland.org. It has good info.
