I'm glad to hear that you were able to save your genealogy files. I took mine with me when we evacuated for Hurricane Rita. We live in Cameron Parish. Our house had damage but were are able to live in ours as soon as the flood waters went down so we could get to it. I hope that you will soon be able to return to your home as well.
Dell Rageur was the wife of Sullie Rageur. Her full maiden name was Muriel Audell Fletcher. She was the daughter of Bertha Ramke & Ernest Fletcher and the grandaughter of Mary Ernestine Wilhelmine Wollenhaupt & John Elmer Ramke. She used to visit us a lot and even went on vacation with our family when I was a small child. She died in 1981. She had one son, John Sullie Rageur Jr. We've lost contact with this branch of the family over the years.
I have some info on the Ramke's. There was a great-grand-aunt Winnie who kept up with all of the branches of our tree when she was still living. Another "cousin" sent me some of her info. I used the relationship calculator on my family tree maker software and found that you and my mother are 3rd cousins, which makes us 3rd cousins once removed.
