Breakdown of Residences of Co. A, 15th Illinois-- Part 1: McHenry County

Woodstock--  32
Dorr--  8     (Dorr Township in McHenry Co.  Woodstock is in it.  Named for Gov. Thomas Wilson Dorr.  Dorr was the governor of Rhode Island and an interesting story in itself after he was tried for treason against Rhode Island and found guilty.)

Other McHenry County towns

McHenry-- 2
Algonquin--  4
Chemung--  1
Greenwood--  2  (McHenry County township)
Seneca--  13   (Township in McHenry County, was called Franklinville.)
Richmond--  2
Hebron--  2
Hartland--  2   (May refer to Hartland Township or an unincorporated town)

So, a total of 68 came from Woodstock and McHenry County.

I'd say this was a McHenry County regiment.
