A James McCrary did enlist during the Civil War from Warren county. His residence was listed as Hickory Point, which was in Tompkins township. His record is a bit odd - it lists that he joined Co. K of the 36th Illinois Infantry at "Blanes crossroads, Chattanooga, TN" on 1 January 1864, and was mustered into the unit on 25 January 1864. Apparently, he was a veteran from another unit. He was killed at Resaca, Georgia on 14 May 1864. His age at that time was given as 38. I found no marriage listing for him in the index, and he appears to be the James McCrary who was living with a Ward family in Warren county during the 1860 census. In 1850, he appears with the William Hogue family. I am somewhat familiar with these families, as various members of the family are buried at the abandoned Hickory Point cemetery (associated with the Hickory Point UP church, closed due to the loss of many of their male members during the war). Spelling of the various family names varied widely; I suspect James was a member of the McCreery/McCreary family that still lives in the area today. Most were affiliated with area Presbyterian churches. If I were to guess, I would say Andrew, born North or South Carolina, was an older brother of James, and both perhaps sons of David H. McCrery.
The last time I checked, estate papers were still 15 cents per page from the Warren county courthouse. Some early records were transcribed into ledgers, while others are still original papers in packet form. There might be some mention of him in the local newspaper as well.
