The Castle Garden Database is now online. You can presently search New York passenger arrivals from 1830-1892. http://www.castlegarden.org/ There are far too many matches to post to the list; Cowan - 825, Cowen - 209, Cowin - 39. Reported in the database results are Firstname, Lastname, Occupation, Age, Sex, Arrived, Origin, and Ship. The website says, in part: CastleGarden.org offers free access to an extraordinary database of information on 10 million immigrants from 1830 through 1892, the year Ellis Island opened.... From 1855 to 1890, the Castle was America's first official immigration center, a pioneering collaboration of New York State and New York City. CastleGarden.org is an invaluable resource for educators, scholars, students, family historians, and the interested public. Currently the site hosts 10 million records, and support is needed to complete the digitization of the remaining 2 million records, beginning in 1820, from the original ship manifests. Have fun!
