The beheading of Charles I in 1649, and the rebellion of 1745:

“I remember my great-grandmother, who told me some particulars she remembered of the army of the Pretender coming to Ross, to which place she was riding on a pillion behind her father when she saw the red coats of the rebels, and her father turned round and galloped back to Monmouth, where he lived, calling out, “The rebels are at Ross!” and the church bells rang to call everyone, the yeomanry were called out, and a man and a horse were despatched to summon troops from Bristol, so the rebels were turned back. This was in 1745. This great-grandmother [who was probably Frances, wife of Thomas Probyn, who lived at Monmouth] told me that she remembered her great-grandfather telling her that he had been present as a child at the beheading of Charles I., so that takes you 242 years through three narrators”.  (From a letter written to her grandson Nugent Chaplin by Mrs Caroline Emily Skinner, on 3 January 1891)
