My name is Ann Trujillo and I came across information you had listed for Charles N. Ferguson on familysearch.org today. My great-grandfather is Charles Monroe Ferguson, but brithdates, mother, etc. match up with your entry. From what I can see Charles was the son of Elizabeth and her first husband, Isac or Isom Ferguson. Then Elizabeth married Joseph E. Brown.
My question is how are you related to Charles and Elizabeth? I'm curious to see if we are perhaps related.
