I do not search this surname. I did not find any Machkowsky in the census indexes I have access to and none in Boston. Maybe the 3 listed below, 1910, might help. They may have preceded your Myer Machkowsky family. Also, you might try to find a naturalization in the county court records. Sometimes the record offers many clues.
