I was born Nancy Twibell. My father, Sam B. Twibell is from E. Texas, and knew that his family was from Indianna. While my sister and I were in college in Spokane, we found an Anthony Twibell in the phone book and his aunt had traced the Twibells back to John Twibell, the revolutionary war, and Monahan Co., Ireland. (I don't know the right spelling.) He had 13 children, but only two surviving male children who had kids, so that part of the family only comes from the two brothers. I have a copy of her (the aunt's) geneology. I know nothing about further back.
