I have family that came from Ireland and  settled in Boonton, Morris County, New Jersey, sometime between 1853 and 1856.    John Collins born about 1832 Ireland Mary (Smith) Collins born about 1834 Ireland Thomas Collins  born about 1854 Ireland   and then their next recorded child is   Ellen Collins born 28 Aug 1856, Pequannock (now Boonton), Morris, New Jersey   so they must have come into the country between 1854 and 1856.   Where, what, how, etc., do I search for any passangers lists that might be available when I do not know what port they arrived in?   The husband, John, is listed as a laborer and I have no idea how or why he ended up in Boonton, New Jersey.    Any help or advice would be greatly appreciated.  Thank you - Mary in Virginia USA
