Morgan Co., Ky marriage register 1 lists the marriage on 6 Aug 1823 of Solomon Cox and Louisa Trimble, by Holloway Powers. (This is only the third marriage registered in the county. Morgan county was formed on Dec 1822, so undoubtably more marriages were performed in the first half of 1823, but the county court house may not have been up to speed yet.)
