Re: Father of John Calvert d 1823 Illinois
According to "Descendants of Virginia Calverts", compiled by Ella Foy O'Gorman, publ 1947:
"John Calvert of Elbert Co, Georgia
This John Calvert(No 7001), mistakenly has been called a son of William Calvert of Mason Co, Ky, No 55, who had no son John.A letter to the Western Calvert Heirs Association dated Feb 5, 1913, from George C. Hart, a great-grandson of the above John Calvert, states that his own grandfather George Calvert (son of the above John Calvert) had relatives in Tennessee named Carson, William and Grove or Groves Calvert.These names found in the David Calvert family of Giles Co, Tenn, thus connect the two families - most likely as brothers.As John Calvert died nearly thirty years before the 1850 Census was taken, we have no record of his birthplace.David's birthplace is given as Delaware."
In the 1880 Census, David Carroll Calvert (son of the above John Calvert) gives the place of birth of both his parents as Pennsylvania.This could make John the son of Joseph Calvert, b 1747 or 1748 in Chester, Pennsylvania, d 6 Jun 1817 in White Co, Illinois. In his will dated 5 Feb 1815, Joseph names John Calvert, Joseph Calvert, Robert Calvert, William Calvert, Margaret Cheatham, Nancy Calvert, Deborah Calvert and David Calvert.
There is an Ancestral File which shows that this Joseph Calvert married Jane Swayne; his parents are shown as Thomas Calvert and Sarah Williamson.
