Include Worcester County, Maryland, in Searching For Our Miller's

In searching for our early colonial Miller's, I'm reminded to expand research to include not just Somerset County, but also Worcester County, Maryland, which was created in 1742 from parts of Somerset County.

These Worcester land records dated 740 and 1744 list both a John and Joseph Miller as Justices of the Peace.  Our Miller's had moved north to New Castle County, Delaware, but could these be cousins they left behind?  Only time and more research will tell.
