"The first record of William Sullivan (c1755-c1840) is his listing on the tax rolls of Montgomery County, Georgia in 1798. He is also listed on several Jury and Tax lists and in a few court documents of Montgomery County during 1800-1812. On 14 Dec 1807 a William Sullevant bought 100 acres on Pendleton Creek in Montgomery County, Georgia from William Edwards for $100. This deed was witnessed by Soloman Story and Henry Sulevant and recorded in Montgomery Co. Deed Book H, p. 135-7 on 19 Dec 1812. This deed is William's first recorded purchase of land. On 6 Mar 1812, William Sulevant sold this same land to Abel Akredge for $200. This deed of sale was witnessed by John Sulevant and William Silivant and recorded on 19 Dec 1812 in Deed Book H, p, 139-140. These are the only deeds that the authors have found that appear to relate to William Sullivan (1755-1842). William and his family next appear in the 1820 Census of Montgomery County, Georgia. He also appears on several tax lists and jury lists in Montgomery County during the period 1820 to 1824. He is not on the tax list for Montgomery County in 1827-1829, thus suggesting he moved out of Montgomery County about 1827. In 1830, he is listed as William Sullivan, Sr. living with his family next to the William Sullivan Jr. family in Lee County, Georgia. In the 1840 Census of Lee County, Georgia there is a male listed as age 80-90, living with the George F. Sullivan family. This male, age 80-90, is believed to be William Sullivan (c1755-c1840). There being no further records found on William after the 1840 Census, as well as his age being in the 90's, the authors have assumed a date and place of death of circa 1840 in Lee County, Georgia for William. The names of William Sullivan's wives and children as listed below in this genealogy were obtained from Ms. Estelle V. Lencses of Miami, Florida. They are based on a summary of Ms. Lencses' collection and compilation of Sullivan records. Unfortunately, Ms. Lencses had lost a box of Sullivan records and has thus not been able to document the make-up of this family. The authors have not attempted to confirm that these are the wives and children of William Sullivan (c1755-c1840). They are included here as a POTENTIAL make-up of this family to serve as a basis for further research by the authors and others." Source: Clarice and Joe Burval.
