Hello,
I am also researching some families in District 1, Weakley County, TN. You may already have his biography, but if N. Y. Cavitt was a state legislator from Weakley County, there should be a brief biography of him in volume 1 of the Biographical Directory of the Tennessee General Assembly. We have these books at our local library, and i can e-mail you a copy of N. Y. Cavitt's biography if you would like. In District 1, I am researching the Oates family and two Harrisons, Henry B. and W.I. (William Iredell) Harrison who lived in District 1, Weakley County, TN during the 1840's till the late 1850's when they moved to Conway County, AR. In 1854 W. I. Harrison married Rosean C. Cavitt in Weakley County. Have you come across Rosean C. Cavitt in your research on the Cavitt family?
