I am not a coleman researcher but if you try to look up anyone or anything in Emanuel county you will bump into the Coleman name (I was looking for Jesse thompson of Swainsboro and found a reference to a shooting in which he was involved which took place in the Coleman Hotel)
I have a book that was published by the Swainsboro Forest Blade publishers in 1976 called Emanuel Memories 1776 to 1976. It is written in the form of newpaper articles and bio vignettes. It had 300+ pages and there is a Coleman reference on 2/3s of them. I found several pictures and bios of children of Elisha C. One list had a marriage for Elisha Coleman and Wina Douglas Nov 28, 1841. There is a listing for a Elisha, born April 2, 1789 died Oct 30 1860. He and his second wife Mary Lucretia Scott Coleman helped organize the Hawhammock Baptist church, four miles from Swainsboro off the Canoochee Road. Elisha was the minister in July 1842 when it opened. Charter members included Mary, Lucretia, and Elisha Coleman among others.
There are several bios of children of Elisha but one, Will Coleman places him in Burke county at on point. Will was born in 1819 Aug 2 in Burke county and died in 1898. It states he moved to Emanuel county in 1834 and settled in the Lamb's Ridge area. I guess he moved with his father due to his age..He was captured during the Civil War by Gen. sherman's forces near Ft. McAllister Married mary Ann Sutton.. children Mary Jane, James, Elzie, Demaris, Alfred Inman, Addison, Sarah, William Berry, and Fanny brought up the rear.After the death od his first wife (who can blame her!!!) he married Martha Banks.. one child Leona Banks.
All of this was on two pages... There is a lot more but I don't even know if this is what you are looking for so I will stop.
There is another book, called Footprints Along the Ohoopee that may give you the info you are looking for. I have a copy of it but I can't locate it at the present. I hope this gives you a lead or two..... Candace Jeffers Smith
