The Reuben of my family line is believed to be with his wife, both between age 16 and 25, along with Delilah's son by Shirley, a male under age 10, in the 1820 census of Barnwell Dist., Barnwell, S.C. on Image 38 of 46 pages in Ancestry census records.
Both Reuben Kirkland Sr. and Reuben Kirkland Jr. are together with a Robert Kirkland in the same census located on Image 26 of 46 pages.
Where as the elder Reuben Kirkland's son, Reuben Kirkland Jr., 1792-1871, married Amy Branch raising a family in S. C., Reuben Kirkland that married Absalom Shirley's Widow, moved to Randolph, Georgia where he and his family are found in the 1830 census of that location. Reuben's step son and four of his children, offspring of Delilah, match the age range of known individuals born to their union by 1830. Three more children resulted with the last child born in 1839. Reuben Kirkland died before 1840.
Mistaken as one of their children, a grandchild, Maranda Kirkland, born in 1844, was born by their daughter, Harriet Kirkland, as evidenced by the 1900 census in Graham, De Kalb, Alabama that names Harriet Kirkland as mother to Maranda while living in the household of Maranda's husband, James Asa Fricks. Their are family stories and speculation that Harriet married an Unknown Kirkland cousin with some sort of mystery attached.”
