I copied this page on the Woodward/Woodyard family from our files in the Montgomery County Historical Society:
"Calvert Mason, alias Woodyard, was born in Charles Co., MD in 1766 and resided there on 28 October 1782 when he enlisted at his home in Charles Co. for service in the Revolutionary War, under the Company Commander of Capt. Joseph Marlborough and was taken by Lieut. David Luckett as his boman (sic) and was stationed at Fredericktown, MD and continued to serve until 15 nov 1783 at which time the Army was disbanded and he was discharged.He was an own nephew of Jeremiah Woodyard who died about 1811 in Fairfax Co., VA.He made his declaration in Rappahannock Co., VA on 9 June 1840.Elizabeth Woodyard (b. 1790/91), daughter of Jeremiah Woodyard (d. 1811) who was an own Uncle of Calvert Mason or Calvert/Colbert Woodyard, made oath that the father and mother of Calvert were not married and that their son Colbert was sometimes called after his father and sometimes after his mother.She said that many years ago, he was called Colbert Woodgard, but for some years past he has always been called Colbert Mason.Mason alias Woodyard of Rappahannock Co., VA received pension 3 Sept 1841 for service in Maryland line under Regiment of Gen.

I am not researching this man and have no further information.
