I also am a Leflore. That's my maiden name.
I just checked my files from WFT , vol. 6 #2525. I only saw one Campbel, who was born to James Avery Leflore & Arley Smith, but it has this one being born in Dec 1889 in Massey,Gaines Co., Moshulatubee Dist, CN and died wft est. 1906-1979, buried in Conroe, TX and his wife's name was Grace Brown. This Campbell had 10 siblings. If any of this sounds familiar, let me know. I will snail mail you a complete copy of this file, if you can't get it from WFTmaker.
