Well my common communities are:

Paternal:
Scottish Lowlands, Northern England & Northern Ireland
South West Scotland
Delaware Valley, Chesapeake & Midwest Settlers
St. Louis, Missouri & Western U.S. Settlers

Maternal:
Early Connecticut & New York Settlers
South East England
East of England
The Midlands, England

I have no idea what it really means, just that the DNAmatches on those sides live there now perhaps!
