My maternal great-great-grandfather, Christopher C. "Peter" CARROLL and a Hugh CARROLL, both non-rank, along with Capt. John CARROLL and Sr. 2nd Lt. Samuel H. CARROLL, fought at Vicksburg in Co H 8th Mo Inf, mid-1863.Confederates all, they were together!
"This unit was attached to Brig. Gen. Mosby M. Parson's 4th Brigade of Maj. Gen. Sterling Price's Division, Lt. Gen. Theophilus H. Holmes' District of Arkansas in Lt. Gen. Edmund Kirby Smith's Trans-Mississippi Department and was commanded by Col. S.P. Burns. [Refer to Edwin Bearss' The Vicksburg Campaign, Volume III, page 1243.]"
Peter b 1820 d bef 1880 and his family have been found in the 1850 U S Census of Woodford County, KY, but all four men ended up in (Northeast) Missouri it would seem.Peter's 3 eldest, daughters, were born 1842-1849 in Schuyler County, Missouri.
Is the abovementioned Hugh CARROLL possibly in your lineage or possibly a namesake of the Hugh you have enumerated?
Of course, as with many, I am stymied by my CARROLL ancestry.
I wonder if we could correspond should there be any connection(s) at all.
