Looking for Ancestors

Last week I went to the parish of St Feock in Cornwall to look at a church built by my ancestor William Gerrish, a stonemason born in 1800. The church is set deep in the Cornish countryside, in an area where a lot of my forebears lived, including Penroses as well as the Gerrish family. The only recorded twins in my family tree (until Jade and Jasmine) were William's sons, so I feel a sense of connection to his family. The Saxon church tower set apart from the church building seems oddly familiar too.
