Historians, sociologists and other social scientists have for some time virtually ignored many small, scattered immigrant groups in this country. Researchers have also tended to ignore certain British immi? grants, concentrating their efforts solely on the English, Irish and Scot? tish groups.

Early in their movement, they tended to come as individuals or families who settled in New England and, more significantly, in Pennsylvania.
