“Welcome to Mary’s House!” An open house was held today commemorating the completion of the home built for Mary McGuffin and her family. The home, 550 Beech Top Rd., Columbia, is a four bedroom brick house located in the Cane Valley Community. McGuffin and her seven children lost their home last year in a fire. Businesses and community members throughout the county donated time, supplies and money to help build the home. The family will be able to move in within the next couple of weeks.
