The father of the Warren's listed below is my * brick wall*, the father was supposedly born in Massachusetts.

Walter (1810), Hamilton (1812) and Samuel  (1818) were born in Delaware.

 Walter married Margaret Pritchard in 1832, Margaret was born in Cumberland County, New Jersey. Their family, the first 8 children were born in Murderkill Hundred, but Aaron and Francis ( Frank) were born in Potters Landing, Caroline County, Maryland.

  I have found some maps and if you put them in geographically order you will be able to see the migration of the Warren family.
