I see the source of the marriage in 1610 as shown, but I see no exhibit/source that Edward died Mar 25, 1630. Stating a specific date normally comes with a source, but none is cited. The first son was Grevason Brantley born 1612 according to Parish records of All Saints parish, Evesham, England. Recent research project in England has establish the likely lineage of this Edward back another 3 generations: Project still underway.
