What does "living 15 Rich. II" mean for the year an ancestor was alive in England?
This is a notation used in the British Roots of Maryland Families II by Robert W. Barnes regarding the Bysshe Family.
It also says another ancestor was "living 14 Hen. V and 36 Hen. VI." I thought it may mean the ancestor was living in 1414 since Henry V was ruling at during that year and 1436 since Henry VI was ruling during that year. However Richard II ruled between 1377-1399 so I can't figure out what the 15 in "living 15 Rich. II" means.
