I have been searching for information about this man for thirty years. I have located some living descendants in a direct Avery line, and am about to pursue DNA testing to try to determine which known Averybranch, if any, he belongs. I am curious as to your statement that he was a Mohawk Indian. I have a lot of information about many of his children. Of the eighteen or more born to his two wives, ten are known to have have married and had children.
I would be delighted to share information with you.
