"Philip (Langdon), an innkeeper. … June 25, 1689, Paul Simmons, being bound to sea, appoints his trusty and well loved cousin, Philip Langdon, his attorney."
Estimated birth assumes that Philip would have to have reached his majority in order to have been able to act as Simmons' attorney. This in turn indicates that Philip might have been the child of an earlier, unknown, wife of his father's.
