It is said that Peter David Corbin (Corbin-723) was born 23 Apr 1745 in Stafford, Stafford, Virginia,  the son of John Corbin and Laetitia (Lee) Corbin This is uncertain, in dispute and currently under review.  Peter Corbin (Corbin-723) died abt 30 Jun 1794 in Pendleton, Anderson County, South Carolina 
John Corbin is said to be a descendant of Hon. Henry Corbin, Sr. (1629–1676) and Alice (Eltonhead) Burnham (ca. 1627–1684) (Hall End Corbins).  Henry's daughter, Laetitia Corbin married Col. Richard Lee II (1647–1715) 
One source that has John Corbin linked as Peter's father is Re: Nelson Hester Corbin Sr. of Ok, Al, Ga ', By Carl Fowler September 17, 2004  This source has not been validated and YDna evidence seems to indicate that this Peter Corbin is not the Pendleton, South Carolina Peter.
There is an online source, Diana, Goddess of the Hunt — for Ancestors!, that states there are at least three Peter Corbins being confused with the Peter Corbin that founded the Pickins branch of the Corbins. (Pickins Co., SC was formed from Pendleton Co., SC in 1826.) The three conflated Peter Corbin lineages are said to be:
Peter Corbin, (c1740s- )  of Lexington Co., SC, who married Elizabeth Seawright. Said to be (YDna) I1d 
Peter Corbin, The Peter Corbin (1731-1790),  who lived in Dutchess Co., NY, is said to have married Elizabeth Seabright. This is a conflation of the Dutchess County Peter Corbin with the Lexington County Peter Corbin  Said to be (YDna) G2a 
Peter Corbin, (1745- ) of VA, who married Easter/Esther Holdway Said to be (YDna) I1 (presumed from descendant test)  Note: This is the Peter Corbin born born 23 Apr 1745 in Stafford, Stafford, Virginia, said to be the son of William Corbin and Sarah (Unk)  This Peter died before 1 Jun 1782 at Culpeper Co., VA...His widow, Esther HOLDWAY married Philip EDWARDS on 19 May 1788 at Culpeper Co., VA.
The Peter Corbin, of Pendleton, South Carolina, that married Elizabeth (Unk) is presumed to be YDna Haplogroup R-SRY2627. 
The parents of Peter Corbin Corbin-723 are said to be John Corbin of Peckatone, Westmoreland, Virginia, and Lettice Lee Corbin. In addition to Peter they are said to have also been the parents of Martha Corbin, Jane Corbin, and Gawin Corbin.  John Corbin and Lettice (Leticia) Lee are documented as having married 1 Sep 1737
in St Paul's Parish, Stafford, Virginia  Peter Corbin is not listed in the St. Paul's parish register as a child of this couple. There are secondary sources that give John Corbin and Lettice Lee as parents of Peter Corbin, but evidence indicates they had only one son, Gawin Corbin who married Elizabeth Jones 
There is a birth/christening record for a Peter Corbin being born 23 Apr 1745 in Overwharton Parish, Stafford, Virginia, to parents William Corbin and his wife Sarah' This record does not have an image or cite the original source so it's reliability is not known. It is also not known if this record refers to the Peter Corbin of this profile. There are two marriage records for a WIlliam Corbin and Sarah (Fant or Jenkins). Both are located in Overwharton Parish, Stafford, Virginia, one in 1743,  the other in 1744  The reliability of these sources is unknown as the original source is not cited. The children of William Corbin and Saran are documented as being Margaret , Mary,  Peter  and John. . William Corbin is named in the will of his father, John Corbin Jr. 
William Corbin married Sarah Jenkins March 10,1743  He married Sarah Fant August 9,1744 
According to Colonial Families of the Southern States of America, pg 180, John Corbin, 2nd son of Gawin Corbin, married his cousin, Letitia Lee, dau of Richard Lee and Martha Lee, of London. They had three chidren, Martha, who married Col John Turberville, Jane, and Gawin Corbin, of Caroline CO., Va., their only son. John and Letitia (Lee) are not documented as having a son named Peter 
The parents of Peter Corbin (of Pendleton, South Carolina) are currently unknown.
Peter Corbin is said to have married Elizabeth (Seawright) Corbin 1773 in Virginia, however there are no reliable sources that support the marriage. Alternate marriage dates are 1730, 1 Sept, 1737 and abt 1744 in St Paul's Parish, Stafford, Virginia. These alternate dates appear to have come from unsourced family trees.  All of these dates are questionable as their oldest child is documented as being born in 1762, No reliable marriage record for Peter Corbin and an Elizabeth Seawright has been located, however, the June, 1795 will of Peter Corbin (of Pendleton, South Carolina) does mention his wife, Elizabeth. Elizabeth's surname is not known.

It may be possible to confirm family relationships with Peter by comparing test results with other carriers of his Y-chromosome or his mother's mitochondrial DNA.
However, there are no known yDNA or mtDNA test-takers in his direct paternal or maternal line.
It is likely that these autosomal DNA test-takers will share some percentage of DNA with Peter:
