I cannot tell you the father of George, but his mother was Mrs. Mary (or Polly) Hooper. George had siblings named:
Edward (apparently died long before the 1880s, never married)
Thomas (born abt. 1789, died before 1865),
Mary (also known as Polly, born about 1800, never married, died in the 1880s),
John (alive in 1830, left VA), Henry (alive in 1830, left VA), and
Isaac Newton Hooper (b. abt 1805, left VA in 1820s, married 2x in TN, d. Sumner Co., TN between 1850 and 1856).
The above information was derived from census records; tax, school, marriage and probate records in TN; a Hanover County, VA will recorded in Missouri for a different family; and a very informative Chancery Cause in Hanover County, VA
An abstract of the will I mentioned above is available athttp://www.rootsweb.ancestry.com/~momarion/willbook.htm
and another copy athttp://archiver.rootsweb.ancestry.com/th/read/bowles/1999-10...
The Hanover County Chancery Cause of James Hooper v Perkins is available at the Library of Virginia website. Pay particular attention to the genealogical data available at images 42-43. The following is a part of my own abstract, for information provided by a nephew of George W Hooper:
"Testimony by William M Hooper, age 62 and resident of Richmond, regarding heirs at law of Mary Hooper and of Edward Hooper. Land [72 acres at Blackhaw, in Ashland district] was property of my grandmother Polly Hooper and my uncle Edward Hooper, each owning half. Polly died many years ago and Edward after she did, leaving no issue, never married."
