A passion for public records runs in Michael McCormick’s family. His mother, Susan McCormick, has researched about 12 generations of her family tree, building multicolored fan charts of ancestors’ names going back to people living in Europe around A.D. 1200.

Genealogy is important to the Church of Jesus Christ of Latter-day Saints, of which Susan is a member, but her interest in her family’s past goes beyond religion, she said. The Gardners, Pa., resident says her ancestors are present in her everyday life. And she finds them using public records.
