I thought I had copies of all Roberts and Knowles marriages before about 1900, but I can't find this one. I have several marriage records for William Knowles (different ones) but none for a Catherine Roberts at all.

I have a William B. Knowles, b. 1823 in TN, d. 7 Jun 1898 in Limestone Co., AL (unconfirmed data) who married Martha Ann Rascoe 4 Aug 1840 in White Co., TN. I have a copy of their marriage record and their census records through 1880.
