While looking for the records about ancestors in Warwickshire, I found mention of the ‘Train Wreck at Wootton Bridge. On 11 Jun 1861, the bridge collapsed when a passenger train was passing over it. I wonder how many folks would have referenced events in the area based on that event. “That was before the bridge collapsed.” “That was two years after the bridge collapsed” and so on.
Events in the history of any community are always useful in pin pointing a date in the timeline of our ancestors.
