I had recently read in a magazine from a few years ago that for the port at New York ALONE there was a unique entry policy for women traveling alone. It said that single women or married women traveling without a male relative were detained until a male relative came to get her from Castle Garden and possibly Ellis Island.(Not sure when this changed.) Does anyone know if this is true? Has anyone searched the ship's lists and used this to identify that one Mary Benson is the ancestor's sister and now you know where her brother lived possibly in 1883? These detained lists are not part of the records at Ancestry but the article said they would be at the end of the list. Were they filmed for the National Archives films? Thanks!
