Aaron Wickenden asks: How many Wickendens are there living today? Can the model used to predict the growth of the Wickenden population through the seventeenth century be extended through the twenty-first century?
Response - Twenty years ago one could order a printed listing of all the Wickendens around the world who had internet addresses. I believe this is even easier to accomplish today. But the model also could be extended, and if there was a parameter for the percentage of Wickendens who had email addresses, one could adjust the model to get an even more accurate figure than through internet addresses alone. When I have access once again to the printed listing, I will develop an extended model.
