You are correct, I had left out a generation.BT Spiers was the son of Timothy Thorpe Ridley and grandson of Day.Margarate Louisa Rea was also a great granddaughter of Day.ML Rea, just of interest,is descended of Daniel Rea of England and his children who were witnesses at the Salem witch trials.
My info says that Day was a Colonel, but i didnt record the source.I have that his grandfather, Nathaiel Ridley I, was a captain, presumably of the British army or navy.Capt. Ridley is as far back as my ridley line goes, though his wife, Elizabeth Day, I have back a few more generations.
Accoding to a book I have, "The history of hertford county NC" Day Ridley was quite involved in the states affairs at the time of the revolution, including a congress to draw up NC's bill of rights.unfortunately there is no specific info on his military service.
if anyone has any further info on any of these folks please share it.
