The 1880 Lowndes Co GA census shows a James (C.?) Wisenbaker age 37 and wife, Elizabeth age 27, with a Homer Wisenbaker age 3 - makes him born around 1877.
Lowndes Co Marriage Records 1870-1921 shows a Homer Wisenbaker marrying Lannie McCranie, on 8/9/1918 - Book H, page 134.The same records shows James C. Wisenbaker marrying Fannie Lane on 2/10/1881 (1880 in another source), book A, page 378.
The family bible of Augustus and Gertrude Wisenbaker Lane shows following: James Wisenbaker - 1809 birth (definitely not the James C.)death 1868 Fannie Lane - 4/29/1864 birth
James "Israel" Wisenbaker is married to Frances "Fannie" Elizabeth Lane.[the Elizabeth thus matches up with the 1880 census) James is son of Richard Herman Wisenbaker. However, Reba Payne's book on page 136, shows six children of this union and none are named Homer (which may be a middle name of either Augustusor Edward?).
James Israel was born 8/23/1858 and d. 12/23/1918, m. Fannie Lane (page 103 of Reba Payne's book. James appears in 1860 census under Richard H.
His father, Richard Herman Wisenbaker, b. 3/30/1821, was m. to Celia Swilley.
Richard Herman Wisenbaker was the second son of Christian Gottlief Wisenbaker and Mary Catherine. Richard was b. 9/29/1792 the third child of John (I) Wisenbaker and Ann Christina Dasher. Richard m. 1814 to Mary Catherine Waldhauer, b. 12/23/1794.
John Wisenbaker was first son of Christopher and Constance Wisenbaker.
Getting back to James C. Wisenbaker (who may or may not be James Israel above?) - page 142 shows an obit regarding a J. C. Wisenbaker, known as "Jim Stump." He was brother to Lawrence Wisenbaker and was a Confederate soldier. Surviving him were his children: Messrs. Lawson Wisenbaker, Homer, Cleveland and Gover Wisenbaker, Mrs. J.A. Wisenbaker, Mrs. Archie Arnett and Mrs. L. C.McMullen.- Valdosta Times, Nov. 7, 1913.
Richard also had a Lawson in his home in 1870 census; however, this is probably James L. on the 1880 census. Gover and Cleveland were probably born after 1880.
That is about all I can find on the Homer, if he was born within that time frame.
