An article from the Anson Times, Wadesboro, NC, dated February 28, 1884:

February 23, 1884, Rockingham, NC
"Mr. Editor:
By your request, I proceed to furnish for your newspaper an account, imperfect tho' it must be, 
of the cyclone which passed near here on Tuesday night, February 19th. We hear of the first 
stroke from it at a point six miles southwest of this place where an immense oak was thrown 
upon the house of David (actually Daniel) Watson, crushing it in seriously hurting Mr. Watson 
while his wife (Margaret Stewart Watson) and her brother, a young Mr. Stewart (John) were killed".  

It is believed by relatives that it was not the cyclone that actually Margaret and her brother John. 
Apparently, they were standing at the front porch watching the cyclone and the storm knocked a 
shotgun off its place on the mantle discharging and killing them both.
