There was an Edward Allerton in the parish of St Dionis Backchurch, City of London, England about this time. However, the parents of the Isaac Allerton who was the Mayflower passenger have been shown to be Bartholomew and Mary Allerton of East Bergholt, Suffolk, England.
Please would the PGM take a look at the Allerton profiles who are duplicates of the Allerton/Brewster line, and the England Project will look at Edward and Rose.
