Joe Spann is a genealogist and on this day he’s explaining emigration to the American Colonies. “Most of you will have ancestors in one of these groups,” he said, pointing to a projection that lists Scots-Irish, Quaker, English Elite and Puritans.

These are Lifelong Learners, many of them retirees, looking for some intellectual fun. The group is attending one in a series of lectures called KEY Lifelong Learning at Vol State.
