Henry's widow Catherine de Valois (1401-1437) married Owen Tudor, a Welsh squire, and one of her sons, Edmund, Earl of Richmond was the father of the future Henry VII. She was buried in the old Lady chapel and when Henry VII pulled this down to build his new chapel he moved his grandmother's body and it was placed above ground in an open coffin of loose boards near Henry V, where it remained for nearly 200 years.
