The Osborne family was very closely associated with the Phips or Phipps family in, at least, Ashe County, North Carolina. A book titled Descendants of Caleb & James Osborne & Patrick Cragun, by Hone (2013) includes references to a Solomon Osborne who lived in nearby Russell County, Virginia, where he bought land in 1812.
The book refers to what appears to be a deed abstract from when Osborne bought the property. Since James Phipps signed the deed, it sounds as though Osborne bought the land from him. The land was adjacent to land belonging to James Phipps.
