Hi Drakes
Have you found your ancestor in census records after his arrival?
The 1900, 1910 ,1920 and 1930 census identify citizenship status, with notations showing the individual was an Alien, or had started the Naturalization process or had his final papers. They also give the year of immigration. As well, 1920 gives the year of naturalization.
Finding his immigration year from the census would be Step One.
Step 2 would be finding his naturalization records (if he naturalized). These will have an immigration date. See
http://naturalizationrecords.com/usa/ for further help, and for links to online databases.
Step 3 is finding that ships list. Once you know your ancestor's state of entry, you can search
microfilms. Most states are indexed, so this will make your job slightly easier. You can order films in to a nearby Family History Centre, or have NARA do the job (once you have precise details)
Once you know your state, you can get a list of film numbers (NARA & FHC) at

The staff of the National Archives will undertake a search of the original records for a fee but you must know the name of the ship, the date of arrival, and the port of arrival.
There are no published indexes strictly for English immigrants, but there is a search engine that searches the Internet for ships FROM England to USA or Canada
The search engine will search multiple websites for passengers sailing from England to USA.
http://olivetreegenealogy.com/ships/englishtousa.shtmlYou say you searched Boston arrivals 1820-1943 BUT... the problem with the Boston arrivals is there is an 8 1/2 year gap on M277 (which is titled Passenger Lists of Vessels Arriving at Boston MA 1820-1891) The gap is from a April 1874 to 31 Dec 1882.
That is because there are no Federal records of any kind prior to 1883 (due to fire) and State Department copies were used in their place. BUT State Departments copies and abstracts only covered up to end of March 1874.
However the good news is that there ARE records for the missing years. They are not available at NARA, only at the Massachusetts State Archives
I believe though that there is an index on M625 which *does* cover those "missing" years. Finding an ancestor on that index in those missing years means you have to then write to
the Mass. State Archives for a copy of the passenger list page with your ancestor on it.
Good news though -- this JUST went online - the Massachusetts Archives has an online Boston passenger lists index that covers 1848 to July 1891. It is not complete, but it might be
worth checking if your ancestors arrived in Boston during this time frame..
