Background data:James Petticrew (I call him Uncle James since he was the brother of David Petticrew from whom I am descended) came to PA before 1759 (listed in tax roll that year).He married Jean (pronounced Jane) Ainsworth in 1763 in Hanover Twp., Lancaster (later Dauphin) County, PA.They had five sons:William, John, Robert, James and Samuel; and one dau Elizabeth.William married Isabel _?_ in PA and John married Mary Ward in PA, both shortly before 1790.William and Isabel had a son James born in 1791, and Samuel, the oldest son of John and Mary, was born in 1790 (christened in 1791.)The other four children were not yet of marrying age in 1794, when Uncle James sold his 100 acres in Hanover Twp. and moved the entire family to Rockbridge County, VA.There he purchased a 150-acre "plantation" in 1794.The following year (1795) William bought a tract nearby, as did his cousin, John Finley Petticrew (my ancestor).Uncle James' son John "occupied" 38 acres of his father's plantation, on which he was still living when he died in 1830.Old Uncle James died in 1799 and left a will which names his wife and all of his children.Among other bequests, he left John the 38 acres he occupied and left Robert the rest (112 acres) of the plantation.Note that the surname of this family was PETTICREW, as well-documented in PA and VA records.
Both William and John had offspring born in Rockbridge County, VA from 1794 onward (as did John Finley Petticrew and his wife "Betsy").Robert, James, Samuel and Elizabeth were all married from 1802 to 1813.In 1806 John F. (referred to as John, Sr. in Rockbridge Co. records to distinguish him from his cousin, John, husband of Mary Ward) sold his original parcel, purchased in 1795, and moved his family to northern Montgomery Co., OH, to join his brother (another James!) and his older sister, Rosanna Campbell.
In the very early 1800's it appears that all of Uncle James' boys were spelling their surname "Pettycrew" (also evident in the Rockbridge Co. records).But then a strange change took place!John changed the spelling of his name and that of all of his family to PETTIGREW!This appears to have occurred sometime between 1810 and 1816.If you have a copy of the marriage bond for his daughter, Ann and Peter Barger, you will note that the scribe wrote "... we Peter Barger and John Pettycrew are held ...", but the document is signed by "Peter Barger" and "John Pettigrew"!This difference shows up on several of the marriage bonds in that period.A clear example is the consent, in 1817, by William for his dau Jane to marry David Parsons.He signed "William Pettycrew", and witnesses signed as "John Pettigrew", "George Parsons" and "Robert Pettycrew".
John's oldest son, Samuel PETTIGREW (brother of Ann), moved into the town of Lexington, and on 2 Jul 1817, he married Hannah Gamble.(I note that you show one of Ann and Peter's children was named "Hannah Gamble Barger"!)Samuel died in 1842 and is buried in High Bridge Church Cemetery as you say Ann and Peter are also.
Sometime after 1817, some of William's children, and finally William himself, moved to central Ohio, in the same locale where his cousins were then living.Uncle James' son Samuel also moved to that part of Ohio and ~may~ also have changed his name to PETTIGREW.His records are mixed.James, Jr. (married in 1802) disappeared from Rockbridge Co. before 1810 and Robert sometime after 1820.So, from about 1820+ onward, only Pettigrews (descendants of John and Mary Ward) remained there for the rest of the 19th century.
I am confident (but without proof) that George Washington Pettigrew (1801-1877), who married Mary Parsons and moved in 1832 to the same area in Ohio as all the rest, was also a son of John and Mary, hence a brother of your Ann.It is not impossible that William was his father, but I don't believe so, because all of William's children that I know about retained the "c" spelling of their surname.
Hope some of this makes sense and will be helpful to you.As a footnote, I want to extend my compliments on the tremendous job you have done in documenting ALL of your ancestor trees for so many generations!Great work.
