thanks again for sharing the Galveston and San Tone (family name for San Antonio) newspaper articles.....!!!!!
Apparently several of the 11th & 17th Arkansas vets were also passing around mug shots and/or descriptions of both Joab and Mack Brown during their Reunion, July 24-25, 1889 (Held in Malvern, Arkansas as documented in the Arkansas Gazette newspaper, July 25 & 26, 1889)
From the article in the Arkansas Gazette, Thursday, July 25, 1889:
"This concluded the business of the hour and the comrades gave themselves up to relating remininiscences indulged in by Lieut. Curl, Capts. Warren and Simms and Judge Cobb of Grant County. They related some very interesting anecdotes which were brought to a close by the receipt of a letter from Col. W.F. Morton of Dallas, Tex., addressed to the Eleventh and Seventeenth Regiments, urging them to assist in the capture of the Brown brothers, the assassins of Col. John Griffith recently. The letter was accompanied by the photos of the assassins. Every member present had a look at the pictures and it is safe to say that it would not be healthy for the Browns if they had been in the vicinity of the camp when the letter was being read. A recess was then taken till 3 p.m."
As best I can figure out, the two witnesses to Col. John Griffith's murder mentioned in one of the newspaper articles you shared were his wife and his young daughter.
