Anne, yes, both ancestresses were born before 1820. So I think you're
suggesting to concentrate on 1609 through 1720 as the most prolific period
for
possible immigration of their ancestress in common?


Lisa,

You will need to start from where you are, but yes, based on the historical
immigration patterns, if your ancestresses were born here before 1820, there's
a higher probability that their common ancestress was already here by 1720
than that she wasn't. By 1720 or so, the colonists were producing sufficient
population growth (largely by having families about twice the size of the
families back in the UK) that recruiting new immigrants slowed down to a
comparative trickle and by the time Revolution came it virtually stopped. While
it's not completely out of the question that your common ancestress was "back
in the old country" and you two have different immigrant ancestresses, it's
less likely than being descended from one woman already here by 1720. Please
don't ask me to put exact probabilities on it, because I don't have them.

Anne
