Bess of Harwick after being widowed three times married the Earl of Shrewsbury and the pair served for years as the jailers of Mary, Queen of Scots. Gilbert Talbot, the eldest son of the earl by his first wife married his stepmother's daughter Mary, and they were the parents of the Countess of Kent. Like all the great ladies of her time, the countess knew about domestic medicine and practiced it in her home and went on to invent medicines as well. The Countess of Kents powder, good against all malignant and pestilent Diseases: French Pox, Small Pox, Measles and Plague added the common daisy to her formula which included expensive drugs such as pearls, gold,coral, jet, and other ingredients beyond the means of common sufferers. Her other specialty was the treatment for sore eyes and "Web over the Eye". Daisies have been used in heraldry. Marguerite, the French word for daisy, is derived from a Greek word meaning "pearl". Francis I called his sister Marguerite of Marguerites and the lady used the daisy as her device, So did Margaret of Anjou the wife of Henry IV and Margaret Beaufort, mother of Henry VII. St. Louis is said to have had a daisy engraved on a ring he wore. Along with it was a fleur-de-lis and a crucifix. This ring, the king claimed, represented all he held most dear: religion, France and his wife, Margurite.
