There were 3 "William Eversole"'s in Kentucky units in the Civil War, though it appears as if there were 4, since there were 2 in the 14th Cavalry, and 2 in the 6th Cavalry. The 4 of them are regularly mixed up and switched around, so this is an attempt to straighten the mess for other researchers who can now apply the proper service records to the appropriate individuals. This problem is furthered by the fact that even Fold3.com has mixed up and switched around the service records of the 2 William Eversole's in the 6th Cavalry, even though it's clear they are 2 different men. The following is my explanation of sorting out the service records for the “four” William Eversole’s, and applying them to the three appropriate persons.
First: There are 6 William Eversole's in the 1860 Census in Perry County and its surrounding counties. Of those 6, only 4 of them are of age to have fought in the war. One of those 4, William son of Rowlin Eversole and Lucinda Campbell, was disabled according to the 1860 Census. So that made this a little easier; match the 3 William Eversole's in the 1860 Census with the 4 William Eversole's in the 14th Cavalry and 6th Infantry.
1. The first William is the easiest to sort. Private William Eversole of the 14th Kentucky Cavalry is listed as 45 years old. The 1860 Census has only one William even close to that age, and it's a pretty spot on match: There's William Eversole in Owsley County, Kentucky, born about 1814, which is a perfect match. This assertion is further verified by the 1890 Veterans’ Census where in Owsley County you can find “William Eversole” where he lists himself as a member of the 14th KY Cavalry. So the Private William Eversole in the 14th Cavalry is the William Eversole (born 1814) in Owsley County in the 1860 Census. This William Eversole is the son of Woolery Eversole and Lucy Cornett.
2. The second William in the 14th Cavalry is listed as 25 years old. He is the "W B Eversole" born about 1837 who is found in Owsley County, Kentucky in the 1860 Census. He distinguishes himself from his first cousin, William, who was killed as a member of the 6th KY Infantry, in his interview with John Dickey. In Dickey's diary it reads, "William Eversole, son of [Joseph], died in the army, on Clear Creek in Bell County in 1862. He belonged to the 6th Kentucky Cavalry." The entry itself actually says son of Jacob, who would be William's great-grandfather, but it's clear he was referring to the son of his great uncle, Joseph, as he is speaking about Joseph in the paragraph, and did not previously mention his grandfather having a son named William when he listed his grandfather's siblings. He is also the William Eversole who is listed as 24 years old and a member of the 6th Kentucky Cavalry; his Civil War Pension lists him as a member of both the 6th KY Cavalry and the 14th KY Cavalry. He was originally charged with desertion from the 6th Cavalry according to his service records, but those charges were dropped as he was discharged for a promotion. This is evident by the fact he was a Private in the 6th and a Captain in the 14th. Unfortunately, he does not appear in the 1890 Veterans’ schedule, but he is in the 1900 Census, so he was not deceased. So the Captain William B. Eversole in the 14th Cavalry and the Private William B. Eversole of the 6th Cavalry are the same person and he is the W B Eversole (born 1837) in Owlsley County in the 1860 Census. This William Eversole is the son of Joseph Eversole and Sallie Bowling. He is William #1's nephew.
[Also note: Almost every online tree I’ve found has William’s year of death as 1909, but with no proof. As he is alive and well in the 1910 Census, this is not a correct assertion. I have not found a headstone or death record proving when he died, but it was after 1909, so researchers should note that in their information.]
3. The first William Eversole in the 6th Cavalry's service record is listed as age 30. This would be the William Eversole mentioned in Dickey's diary by William #2. This William is the son of Joseph Eversole and Henrietta Oliver. This can be confirmed by the 1850 and 1860 census, which each show him being born in 1829 or 1830. Also, his last child, Amanda, was born in 1862. This William Eversole's census records indicate he died April 30th, 1862 at the Union camp at Cumberland in Bell County, as mentioned in the diary. In the 1870 Census, this William's wife Jane Combs, does not have a husband and appears widowed. So that means this Private William Eversole, who is age 30 in the 6th Cavalry's service records, is the "Wm Eversole" in the 1860 census in District 1, Perry, Kentucky. He is the son of Joseph Eversole and Henriette Oliver. He is the 1st cousin of William #1 and the 1st cousin once removed of William #2.
Hopefully this will help other Eversole researchers with applying the proper service records to the appropriate individuals.
