Hi.I'm descended from this same couple.This is what I got from my internet research so far:
John Covington Jr. was the son and one of 11 children of John Covington Sr., b. 1710/13, Church Hill, MD, d. early May, 1767, Queen Anne Co., MD, who, on July 13, 1731, marr. Mary Airey, b. 1709, Queen Anne Co. MD, d. 1744, MD, and they lived on a plantation called "Providence".John Covington Sr. was the son of Henry (Hampton?) Covington, b. 1693, Kent Co., MD, d. July 31, 1744, Providence, Queen Anne Co. MD, who, in 1712, in Queen Anne Co., MD, marr. Sarah Hawkins?, b. 1685? (or Rebecca Chesmore??).Mary Airey was the dau of Joseph Airey (or, far less likely, his bro David Airey??, b. 1683, and NOT Thomas Airey, d. Oct 20?, 1765, Dorchester Co. MD!!), who on Nov. 10, 1708, marr. Mary Baynard, b. 1690, Talbot Co. MD.Joseph Airey may have been the son of Jane (Parrott??) and Joseph Airey (elder), b. 1657?, Talbot Co. MD, d. bef. June 1, 1731, whose family may have come to MD from Kendall, Yorkshire, England.These Aireys were probably Quakers.
I included unlikely connections for the benefit of the meticulous researcher, but for all intents and purposes, I'm satisfied that Mary was, in fact, the dau of Joseph Airey.But as to his origins, I run into a brick wall at Kendall.There's a huge and well designed Airey website from the UK, and it has some lines in Kendall, but I've never been able to establish a connection.Incidentally, I don't know if you put any stock in things like this, but this ancestry goes back to the Plantagenet dynasty of England and pretty much every royal house in Europe, right back to the Roman empire (Theodosius) and King David of Israel.How do ya like them apples?
