My ancestors all arrived in North America long before 1892 the last in 1871. My wife's all came after 1892.
And Ellis was NOT the only place. per wiki: "In the 35 years before Ellis Island opened, over eight million immigrants arriving in New York City had been processed by New York State officials at Castle Garden Immigration Depot in Lower Manhattan, just across the bay."
and "From 1910-1940, Angel Island was an immigration station where immigrants entering the United States were detained and interrogated. The Angel Island Immigration Station, located in San Francisco Bay, California, is rich in history and has served multiple purposes."
