Timothy and Sarah Walker helped settle Concord (Rumford) about 1726. Timothy was the first parson in the settlement. He and Sarah had one son who became a judge and four other children, one of whom died in early childhood. A garrison was built around their house and other houses near them in 1739 to guard the neighborhood from Indian raids. A trust fund, the Timothy and Abigail Walker Lecture Fund, provides wonderful entertainment to the residents of Concord to this day. Concord has Walker Street and Walker School. The school was built on the site of the Old North Church in 1873 after the church burned down three years before. http://www.theconcordinsider.com/article/finally-the-answers-to-our-wicked-hard-insider-quiz?page=full
