My grandmother, Ruby Scritchfield (1895-1972), was raised in Sabine Parish, the daughter of Dr. J. H. Scritchfield. He died in 1905 (pretty young, maybe 30's, but don't have my records with me). I have found mention of John and William in Sabine Parish records and assume they are related but don't have proof as yet. My grandmother had a brother, Joseph Britton S., and William Britton Scritchfield is listed as a private in the 12th La. out of Sabine. Another reason to think they were related. I believe Joseph lived in Lake Charles, La. and has descendants there. I am checking on that.
If you find out more, let me know.
