Do you have any information on the ships on which the Crowders came?What region/town/district did they come from in England, or have you gotten back that far yet on your Crowders?If we were to assume that George Pentecost might have come over on one of these ships from the same area, it would be helpful to look at other known records of the time and place in Virginia.
We do not know much about the Scarborough family....which the Pentecosts are probably linked with - (hense the name Scarborough Pentecost), but this is another family with documentation from nearly the beginning of Virginia, which would be helpful to look for to see what areas/ships they came from.
There is only one Pentecost who was in the Colonies prior to the 1700's....that was John Pentecost (a seaman) at Charlestown, Mass in 1638.He did have a son....also named John b. 1659.We have no proof at a connection to him.So, we are back at looking for George P. and wife Jane (migrating directly from England).
I would appreciate hearing from you about any new information you locate, and I will do likewise.
