Cleveland and Jane had at least eight children [no sources]:
George W., born 1801, died Aug. 28, 1856, married Nancy LNU. Their children were Albert, Franklin, Martha, George, Jane, Nancy, Sally and Mary. All were born between 1825 and 1850 and probably in Adair Co., KY
Humphrey, born c1805; Elijah, born c1807, died c1876, married Lucy LNU, probably in Wayne Co., KY
Elijah - see below.
Walton, born c1810, married Margaret Green May 21, 1837 in Russell Co., KY. Children were Catharine, Green and George, all born between 1838 and 1844.
Martha, married Gabriel Hayes, Jr., Dec. 23, 1813 in Adair Co. Children were Joseph, born Dec. 8, 1822, and D. L.
Elijah was born c1807, and died c1876. He is thought to have married Mariah or Mary Coffey May 18, 1826 in Russell Co., KY. Mariah is said to have been a daughter of Eli and Mary Coffey Coffey. She was born Jan. 17, 1802 in Kentucky, and died Oct., 1855 in Russell Co.
Their children were: Emily Caroline; Lucy Jane, born Jun. 27, 1831, died Jun. 6, 1907, married William T. Jackman, born Mar. 27, 1829 in Russell Co., died Sep. 7, 1891 in Adair Co.; Mary E., born c1833; Mariah, born c1838.
Some researchers have named Robert Pierce as a son, but he was a laborer on Elijah's farm in 1860, and was not related. He is likely the same Robert Pierce who married Elijah's daughter, Mary E., and found in the 1880 Casey Co., KY census. Robert Pierce was operator of a hotel in 1880, and probably the same hotel that Elijah, Sr. ran in Casey Co. in 1870.
Included in the 1880 census with Robert and Mary E. Pierce, was a widow Polly Coffey, age 50, and several Coffey children: Laura, age 15; Martha, age 16; Sarah, age 13; and Elijah, age 11.
I would apprciate hearing from anyone researching Cleveland and Jane, and especially their son Elijah.
