"Griffith" is the correct spelling of the surname used by the descendents of James Griffith who lived in Muhlenberg Co. during the early - mid1800's. James Griffith (sometimes spelled Griffey, Griffits) was born around 1780, died in Muhlenberg Co. shortly B/4 November, 1839. James Griffith married Jane Rose, also of Muhlenberg County, around the year 1811. Children of the above mentioned James and Jane Griffith are: Samuel A. (b. 1813), Lewis L. (b. 1815), Nancy A.(b. 1820), Nathaniel B. (b. 1828), William H. (b. 1831), and Lenox W. (b. 1835) (All born and raised in South Carrollton, Muhlenberg County, KY).

If during your research you come across any documentation of this Griffith family,and only if this would not create an additional burden, I would greatly appreciate receiving copies of what find. By the way, the correct spelling for another surname you requested is " Casebier". Hope this is some help to you.
