The Church of England have embarked on the largest systematic churchyard mapping project ever attempted. The CofE are working with surveying company AG Intl to produce digital maps of all their churchyards (approximately 17,5000 sites) showing the location of churchyard features, all extant monuments, and incorporating data from births, marriages and deaths registers. When completed these maps will be freely available online through the Church Heritage Record and open a wealth of new research avenues. Caring for God’s Acre have funding from the National Lottery Heritage Fund and Historic England to run a programme of public engagement alongside the mapping, to teach local people to use their maps and to crowdsource data to enrich the record. The aim is to bring social history and built heritage to life in the heart of every parish. This paper showcases the mapping tools and how they might be used for research and public engagement. It will discuss the challenges so far and outlines our plans for the next 3 years of the ‘Our Digital Ancestors’ project.
