• Notes

  He was also crowned King of the Romans in 1256. He was married three times. His first was to a commoner and their children weren't considered legitimate heirs. His son by his 2nd wife, Sanchia, named Edmund (his 2nd son named Edmund) wasidered the rightful heir. Richard was murdered the same year as his brother, Henry III, but several months before him. The 3 sons from his commoner wife feuded with step-brother Edmund from Richard's second marriage (Known at the Fued of the Four Brothers). The new king, Edward I, resolved the dispute by changing the legitimate Edmund (Sanchia's son) to Earl of Cornwell instead of Cornwall. The sons of Richard's commoner marriage, Edmund, Richard and Walter lost their right to inherit the Earldom from this ruling. Centuries later, Queen Victoria dissolved the Earldom of Corwell/Cornwall in 1872 by the only known survivor, Martin Nelson Conrwell who had emigrated to Chicago, Illinois. This was witnessed by his children, Galen and Emily Jane Cornwell. I assume that he lost his title because he and his children and grandchildren all lived in the United States. The 1871 Chicago fire had left this family impoverished to boot. This branch dispersed after these events. The point of this is that Cornwells and Cornwalls do descend from King Henry II and often through King Richard, the Lionhearted. Both names were used in this last branch that held the Earldom from Chicago, Illinois. In a proper sense, their name should have been spelled Cornwell as that was the line of their inheritance.
