I checked the burial records at Buffalo Presbyterian Church in Appomattox and didn’t see any Paces or Walkers. Bettie Kate Johnson and John T. Pace are buried in the Blandford Cemetery in Petersburg, VA. I believe other members of their family are also there. Also, from the web site for National Register of Historic Places: Buffalo Presbyterian Church (added 1995 - Building - #95000395) Also known as VDHR File No. 73-28 VA 659, 0.3 mi. S of jct. with VA 658, Pamplin. (my note: Off of Rt. 460. Also called Buffalo Meeting House.) I've visited the church and it is beautiful. I believe the Library of Virginia has some of the church records but I can't remember exactly what they are or the dates covered. Anne
