John Wesley is said to have included the church in his preaching tour of 1771, and the churchyard also contains the grave of the lexicographer Thomas Richards (1710-1790), perpetual curate of Llangrallo, who published the first full-length English-Welsh dictionary in 1753 and dedicated it to Frederick, Prince of Wales.
