In 1890 a skirmish took place in Henryd Road when a Wesleyan minister attempted to bury one William Williams in the ‘Anglican’ church yard.  The curate of St Benedicts and the Wesleyan minister harangued each other over the grave and fights broke out.  Eventually it was agreed that the burial could take place as long as no gravestone was erected.

The village lost its only pub, The Foresters’ Arms, at the turn of the 20th century.  It is alleged that this was as a result of the pub staying open on the day of Queen Victoria’s funeral, the only house in Britain to do so.  This however seems to be apocryphal as the Foresters’ remained open until 1903 two years after the Queen’s passing.
