Allen line: John Clark, Immigrant

This is really a love letter and a challenge to a future family historian.  Your mission, should you choose to accept it, is to find out more about John Clark.  I have one fact I'm reasonably sure of about the man, and a potential marriage date and name of his wife about which I am less sure.  And as to his birthdate and place, I am thoroughly confused.  So you, someone in the future and whomever you are, are assigned the task of finding out more about this ancestor of ours. 

Every tree that I have looked at gives John's birthdate as about 1606, but there are probably many John Clark's in England that fit that broad description.  There are several dates and places attached to his various trees on Ancestry, but none of them match any other information in the trees.  His wife is believed to have been named Joan.  There are several trees listing a 1620 marriage to John, but this could not be our John if he was born in 1606 or thereabouts. 

One interesting possibility is a record from Hartpury, Gloucester, England from April 30,162, stating that John Clark married Joane Nelme on that date.  I do know that people from Gloucester went to Virginia, so this seems to be a reasonable possibility.  However, his son Abraham is believed to have been born in Weathersfield, Essex, England and that is a long way from Gloucester.  So maybe the Joane Nelme idea isn't as possible as it seems.  We know that John and possible wife Joan had at least two children, Abraham and Ann. 

If the time and location of Abraham's birth is correct, then that would mean John left Virginia no earlier than 1639.  I've not yet found an immigration record that gave me any confidence that this was our John.  The death information I have consistently gives him a death date of 1664 (nothing more specific) in (old) Rappahannock County, Virginia.  This would have been on the Rappahannock river or its tributaries, north of the current city of Richmond. 

That is all that I have been able to locate about John.  There are so many questions, both in England and in Virginia, but I leave them to the future family historian to dig into this untold story, thanking him, her or them in advance.  For now, we only know that he is an ancestor and that he was an immigrant at a time when life was not easy in Virginia.  That is a good reason to honor him.
