I am looking for Texas Abbotts also. My Great Grandmother was Susan C. Abbott, her father's name was George Abbott wife Sarah Adams. Susan married John Anderson Lightsey. She also had a sister named Nancy Abbott. Nancy married my great-uncle George Lightsey. I know that they are from down around Huntsvile and were suppose to have quite a bit of land. Do you think your John is any realtion? Have you tried familysearch.com?
