I am not researching this family, just entering information from one of my books "The History of Hardy County," which states:
"Family tradition related that two brothers came from Londonderry in the North of Ireland with their aged father, suffering various adventures when the emigrant ship was boarded by pirates.The Renick name was more common in County Fermanagh than in County Londonderry in the eighteenth century, but it is still found in Northern Ireland."
"Several Renicks settled at Paxton Township in Lancaster (present Dauphin) County, Pennsylvania.A George Renick died there in 1737.A Thomas Renick filed a survey on land in Paxton in 1739 and obtained a warrant for it in 1744.A William Renick who died in Paxton in 1741 left six children, including a Thomas, who were still living there in 1763."
"The similarity of given names might suggest family relationship, but nothing is known of Thomas Renick's activities before he obtained his grant on the South Branch.He died in 1751.Robert Renick, a brother or cousin, appeared briefly on the South Branch, but quickly moved on to Greenbrier.
"Family tradition related that Felix Seymour, who had known Thomas Renick in Ireland, came to America with his nine-year-old son in 1736.When the father returned for the rest of the family, they were lost at sea.The Renicks raised Felix Seymour, Jr.In 1753 he married Margaret Renick, George Renick's sister.The Seymours evidently lived on the manor.Like their Dutch neighbors, family ties and links of friendship in their former home were important to the Scotch-Irish pioneers."
"Mary Welton, who obtained title to 406 acres on the drains of Lunice Creek in her own name in 1754, later married George Renick.In 1766 and 1771 George and Mary Renick sold this property to Felix Seymour.George Renick was the eldest son and heir of Thomas Renick, to whom Fairfax granted 270 acres on the bend of the South Branch just above Milleson's Mill in present Hampshire County in 1748.
