Would be interested if you know more about the Lott Green Williams line, since your posting is from some time ago.
I believe that my husband's 5th great grandfather would have been William Williams, a younger brother ofBenjamin, Lott's father.
I have a sketchy line worked out based on other postings that I've found, but do you have anything you could share? Do you know the other brother's of Benjamin, Lott's father? Did lot have a sister named Sarah and if so do you have her birthdate?
Look forward to hearing from you to compare notes.
