There were three distinctly different Hagler families in North and South Carolina in the 1700`s. The South Carolina Haglers were in the Orangeburg District and the immigrant was a Jacob.
In North Carolina there was the family of John who in 1765 settled in what was then Mecklenburg County. There was another John who initially settled in 1765 in what was and remains Anson County on the west side of the PeeDee River. Due to fevers then associated with "bad water" this John relocated to what was Wilkes that is now Caldwell County.
