I added in those sundry Plantagenets, & also Owen Tudor, plus the 3 children of Henry VII & Elizabeth of York who died young, Elizabeth, Edmund, & Catherine. Edmund & Catherine do not have their own listing, but are crammed into the same tomb with Elizabeth at Westminster:
Princess Elizabeth died on Saturday 14 September, 1495 after suffering from atrophy at the age of three years and two months. Elizabeth was brought from Eltham in state and buried on the north side of St. Edward the Confessor's Shrine in Westminster Abbey on Friday the 27th. Princess Elizabeth was the first of four of King Henry and Queen Elizabeth's children to die prematurely and they were greatly affected. The large sum of £318 (£155,479.74 in today's money) was spent on her funeral and Henry erected a small tomb to his daughter in the Abbey made from Purbeck and black marble. On top of the monument is a finely polished slab of black Lydian, upon which were placed inscriptions to Elizabeth and her effigy of copper gilt, both of which are now lost. Later, Princess Elizabeth's younger brother Prince Edmund (who died in 1500 at the age of 15 months) and her younger sister Princess Katherine (who died in 1503 shortly after birth) were also laid by her side.
OK now "atrophy" is a weird cause of death! Some sort of wasting disease? Like what? Anyone care to speculate?
