Julia, just as a suggestion. It is possible that you Edward might have been related to Isiah. At any rate, a scan of Quaker records might be helpful. That marriage minute was from the New Castle Meeting but, it was found in the Kennett Square Meeting records. There were many catastrophic events that occurred in the first couple hundred years of our history that greatly affected the keeping of records. I understand that a monumental mass gravesite is in front of the Quaker Meeting House on Fourth St in Wilmington and that some many died in a short period that recordsare almost non-existant of that time. Typhus and other diseases took a heavy tool on earlysettlers.I will keep an eye out for your Blake.
