The earliest American Barneycastles lived in Accomack, VA, c1700, which is about 40 miles from Maryland. Frederick was likely born in Maryland as his accounts and records are all in Maryland. He enlisted in the Flying Camp Militia of Maryland in 1776, his first service was in the Caroline County Flying Camp, and he was part of many battles during the American Revolution including Harlem Heights, New York, New Jersey, the group was commended for their courage in battle in a letter by George Washington. He later served in the Wicomico Battalion in Maryland in 1781. After the war he lived in Wicomico Hundred, near Salisbury, as found in a 1783 survey tax list. He closed his store accounts with John Nelms of Salisbury in 1787, and moved up to PA, perhaps around York county, and then down the Great Wagon Trail to what was then Rowan County, NC around 1790. He bought property in Clemmons on the east bank of Muddy Creek, just at the Moravian boundary line. His property was in the original Rowan County, which was redrawn to become part of Stokes & then Davidson counties. His descendants lived there and in Forsyth County. He married Elizabeth Kessler. I'm pretty sure Frederick's father was the older Samuel found in Rowan tax lists, who came from MD to live with Frederick in 1810 and died soon after. Frederick's oldest son was named Samuel. Frederick's children: Samuel, Esther/Hetty, both born MD; John born PA; Peter, Hannah, Francis, Elizabeth, Leah all born NC. He was likely buried on his farm as was Elizabeth. His farm was located on the banks of Muddy Creek, at the Moravian border, and is near the boundary of present day northern Clemmons in Forsyth county. At the time of death his property was considered Stokes county, though he also owned 3 acres in Old Salem. His property was listed in the tax lists of both Davidson and Stokes; the boundaries changed a few times. His probate records are found in Stokes county.
