Arguments for Mary McCoy, wife of Leonard White, being the daughter of John McCoy
by Susan Brooke
Aug 2020

Mary McCoy who was born about 1743 married Leonard White, son of Captain John White. She was identified as "Mary McCoy" by her niece, Margaret White Geary. (1).  John McCoy and Captain John White, the father of Leonard White, lived fairly close to each other. (2)  As the children of John McCoy and John White grew up they also obtained land in the area.  Peter White, brother of Leonard White, had 60 acres on "End of Strife" surveyed in 1754 with a resurvey for 310 acres in 1759. This land was in Funkstown practically next door to where John McCoy lived. (3)
There were other families named McCoy in the area. (4) However, the evidence points to John McCoy being the father of Mary McCoy. (5) 
The first time John McCoy shows up in this part of Maryland is 11 May 1739 when he and Daniel McCoy signed a petition to the governor for a new county. His signature is recorded below.(6)  He was granted 150 acres of land called "Neglect" in 1742. (7)  In 1746-7 John McCay and John Martin served together as road overseers for the Monocacy-Annapolis Road. (John Martin may have been a brother to his wife Margaret.) It ran close to the town of Mt Pleasant (where John McCoy owned "Mount Pleasant.") (8)  "Mackey's Delight "was surveyed for John Mackey on July 21, 1746.  It lay immediately south of present day Mt. Pleasant, with a beginning point 'on the west side of the wagon road leading from Monocacy to Annapolis, near the head of a spring running into the Linganore.' In 1749 John Mackey and his wife Margaret conveyed 'Mackey's Delight' to Isabella Hussey seamstress, for 11 pounds of money and 716 pounds of tobacco."  (9) It is interesting following the path of this plat of land. It abutted the land of James White, brother to Leonard White. (10) The last we hear of John McCoy is 19 Jun 1750 when he and Margaret were selling land called Mt. Pleasant for £30 (11)
John McCoy seems to have died before Nov 1762 when the boundaries of Mackey's Delight were being resurveyed. (12)
John McCoy was definitely the father of Archibald McCoy as Archibald mentioned his father in his will.   And the John White family and the John McCoy family obviously knew each other very well.  John White's son, Leonard White, married Mary McCoy around 1761 who was probably the daughter of John McCoy.

SOURCES

(1) Mary, the wife of Leonard White, was named as Mary McCoy in the reminisces of Margaret White Geary. As recorded in the Testimony of Margaret White Geary, "In the year 1846 (1848), the Rev. Edward Ratchford Geary wrote as follows: 'Some account of my ancestry as obtained this evening from my Mother, Margaret White Geary. ' "
Margaret White Geary was a niece of Leonard White as her father, Peter White, was a brother of Leonard White.  Her recollection as recorded by her son: "Leonard married Mary McCoy and settled in Fayette County, Pennsylvania.  His widow married Benjamin Bloomfield."

(2) John McCoy and John White lived close to each other

John McCoy had 150 acres on "Neglect," located in what later became Funkstown, surveyed on June 8, 1739, marked in green below. *

John White was granted a warrant for 573 acres on the Potomac River on 18 Feb. 1749/50. It was about 3 miles from the land of John McCoy and is marked in red below. #

On 19 Nov, 1766, Leonard  and Mary White sold a tract of land containing 144 acres called White's Delight and Old Fox Deceive. This may be land marked blue on the map below.   #

(3) End of Strife
http://washingtoncountyhistoricaltrust.org/19-ravenswood-circa-1784-funkstown-md/

"When Hagerstown was first being settled, John Stull was a large property owner and was active in organizing Washington County. His daughter Margaret married Peter White, and it was to him that a land grant for 370 acres, named End of Strife, was given in 1755. Peter White’s daughter Sara married John Wagoner; and Peter’s 1784 will indicates that she had been given a five acre parcel of this tract situated on the west side of the road. The will also gave her a cow and a female slave. By 1797 John Wagoner had purchased the remainder of End of Strife from his wife’s mother and brother." John Wagner built and historic house on this land that is located at 19 Ravenswood Drive in Funkstown.

 (4) Other McCoy families in the area

Calendar of Maryland State Papers No 1: The Black Books pg. 22 -- Prince George's County List of taxables in Rock Creek Hundred, taken by David Jones, constable. -- William Mc Coy.
This John McCoy not old enough to sign the petition in 1719? But old enough to have a son born in 1732.

A William McCoy was on a tax list for "Rock Creek" in 1719 and then seems to disappear.  Another William McCoy appears in 1754 acquiring 30 acres on  "Strife" which was described as being near Sugar Loaf Mountain which is 35-40 miles from Funkstown.  He is young enough to be a son of either the disappeared William McCoy or a son of John and Margaret McCoy.  He had a daughter named Mary who married a Boyd.  There was also a  Daniel McCoy who seems to have started his family around the time he acquired his first land in 1749.   His land was on Beaver Creek which is about P 37 on the map.. He is probably related to John McCoy in some way, and he did have a daughter named Mary but she married a Forker. Archibald McCoy was definitely a son of John McCoy and he also had a daughter named Mary but she married a Powell.

(5) Evidence that John McCoy was the father of Mary McCoy

a. John McCoy lived very near Captain John White

b.  Archibald McCoy, the known son of John McCoy, served in Captain John White's muster roll for the French and Indian was in 1758.  John White was captain.  Listed in his unit were Ensn. Peter White, Sergt. Leonard White, Corpl. Archibald MacCoy and Private Daniel Maccoy. (4)  There is no mention of a William McCoy even though he is recorded in deeds later on.

c.  I have several DNA matches to Archibald McCoy of Washington County, MD, born 1732 and married to Elizabeth Blair, and two of them are rated "good."  The DNA tree named D.S.(bobbyschrull) takes me to the right family and has a match of 30 centimorgans.  The tree of Louise Russel has 26 centimorgans and the B.B. tree (Morrison Family Tree) takes me to John Ward McCoy, a grandson of Archibald McCoy, and that match is 24 centimorgans. 
When I check these trees for "shared matches," I find that they are all sharing with each other, which leads me to believe, the intended match is indeed a McCoy match.

11 May 1739
Prince George's County Petition of various inhabitants of the back parts to Gov. Samuel Ogle and the Upper and Lower Houses of Assembly
The court of judicature is from 120 to 200 miles away; many vagabonds steal horses and cows, but the injured party would rather suffer such loss than go to the great expense and trouble of prosecuting; also he would suffer the loss of any debt rather than apply to the court of judicature for justice; the sheriffs never come to demand or give any account of officers' fees or taxes, but if the inhabitants come to court, they are taken in execution; the petitioners therefore pray that the county may be divided and that the court house may be erected at Salsbury Plain.
