This was in the Collin Co.book by Stambaugh quoted from the 1906 McKinney Paper article and the Grayson Co.book.
I do not have the Dec.22,1906 McKinney paper or the Grayson County history book(Lucas & Hall p.146). Stambaugh used those to write his article. Try"Portals to Texas Past" online to find the McKinney paper. I think I tried to look for it back when we were discussing this and may not have been able to find it. The Grayson Co book is somewhere. You need to find this. It is likely the Wilson incident was mentioned as it would have been big news at the time.
I put out queries on many of the Collin Co. sites and also sent a copy of the Captain Hall "Yankee Killer"article but never got a response.
