I am a member of the Brazos Genealogical Association (not a CAUSEY descendent). Here are a few notes which might help:
*P.N. CAUSEY appointed to office at Wellborn, Fort Worth Daily Gazette, 17 Sept. 1885, p.4
*P.N. CAUSEY, justice for Wellborn precinct, visited Bryan, (weekly) Bryan Eagle, 23 Jan. 1890, p.5, col.3.
*Anna CAUSEY married A.W. ROYDER, (weekly) Bryan Eagle, 13 Feb. 1890, p.8, col.3; 20 Feb. 1890, p.1, col.5
*P.N. CAUSEY was a candidate for justice of the peace, (weekly) Bryan Eagle, 22 May 1890, p.5, col.3
*P.N. CAUSEY brought in the 1st bale of cotton to Wellborn, (weekly) Bryan Eagle, 4 Sept. 1890, p.1, col.4
"Death of P.N. Causey," (weekly) Bryan Eagle, 24 Apr. 1902, p.2,col.1
I hope this is helpful.
