Former Hingham Citizen of the Year Thomas J. Carey Jr. will be the keynote speaker during this year’s annual Lincoln Day ceremonies. A law professor at Boston College, Carey was given the recognition in 1998 for leading the drive to repurpose the Central Junior High building into what is now Hingham Town Hall. “Tom Carey can speak firsthand about the community spirit that Lincoln Day celebrates,” said Suzanne Buchanan, executive director at the Hingham Historical Society. “He has served on numerous Hingham committees and boards, as well as teaching classes at the Senior Center.” The annual event recognizes the legacy of community exemplified by President Abraham Lincoln and his forbearer Samuel Lincoln, who settled in Hingham in 1637. This year’s celebration on Saturday will begin at 10:15 a.m. at the Old Ship Church and conclude with a walk to the Lincoln Statue for the laying of wreaths. A reception will be held at Old Derby Academy. Full story for BostonGlobe.com subscribers.
