Robert McHenry is mentioned in The Dugger Family by Francis Dugger Rowan.Here is what she says about him (p. 6-7):
"Mary Brown (b: 1790-d: after 1870). Little is known of Mary Brown and her ancestry; and it has not been determined the name of the Brown that she married.There were many early Browns in the Carter County area at the time.
"Family tradition states that Mary came from Ireland with her parents, the McHenry's when she was two years old, (1792).However, records do not 'bear this out,' even to the name. Census records all say Mary was born in Maryland.By other early records it appears that Mary was the daughter of John Primmer and that her step-father was Robert McHenry.
"John Primmer came from Maryland to North Carolina and died in Washington County, N.C. in 1792 (which was later the Carter County area).He and his wife, Mary, had at least four children:1.Hester, who married Joel [Wayne] Dugger, 2.Rebecca, who married Benjamin C. Dugger, 3.James, who married Sarah Buck on July 20, 1816, and 4. Mary, who married __ Brown.
"It is thought that John Primmer was drafted, or enlisted in an expedition against the Indians in 1792 and was killed in battle.John Primmer's Estate Inventory is listed in the Washington County, NC Estate book (1770-1821) (page 87), filed August 1794.Besides 100 acres of land, he had several head of cattle, one horse, and the usual household items.Estate filed by Cornelias Bowman, Jacob Smith and Peter Bullinger.
"John Primmer's widow married Robert McHenry in Carter County, September 23, 1796.I have a copy of the marriage certificate, signed by the County Clerk, George Williams.Since Mary's children were still quite young when their father died, they could have easily gone by their step-father's name McHenry (or at the least, family tradition remembered it that way.)
Before his death, John Primmer had entered land, which was finally granted in 1794, and later sold to the McHenry's by James Primmer, son of John.
Robert McHenry and Mary Primmer McHenry had five children.1.Andrew, who married Theodicia Heaton; 2 Hugh, who married Mary Rasor on May 11, 1817; 3.Nancy, who married Charles Hayse on April 29, 1822; 4. Margaret; and 5. Mary, who married a Sheets.Robert McHenry was still living in Carter County, (1830 Census) age 70/80, which indicates he was born between 1750-60.Deed records show that Primmer and McHenry's land was close by one another in the Cobbs Creek area, which is now Johnson County.Robert McHenry appears to be the only early McHenry pioneer in that area in 1790-1800; seemingly the only possiblity for Mary Brown's connection to the McHenry line."
My line is through Mary Brown.I'd like to hear any info you have on Mary.
