Anyone for tennis?

There is an issue with Edmund the Martyr, King of East Anglia, who was shot and beheaded by Vikings, today in 869. He isn’t England’s patron saint, although he is far more English than St. George, who is thought to have originated in modern-day Turkey or Syria. However, unlike St. Edward the Confessor, whose brother-in-law Harold II and great-niece Margaret of Wessex are ancestors of centuries of English and British monarchs, St. Edmund does not seem to be connected to our Royal family at all, even though he reigned during the late Heptarchy and counted Raedwald and the other Wuffings among his predecessors. In short, he is a genealogical island.

Now it seems that St. Edmund, as were Richard III, Henry I and other kings, is on the verge of being rediscovered in plain sight, under a tennis court in his case.
