The following guardian bond is an example of the information that can be found. It comes from Loose Guardian Bonds (1842) filed in the Caldwell County Clerk's Office, Princeton, Kentucky.
Washington Watkins was appointed guardian for Miss Delitha Lunnen [Lemmen?] 16 May 1842. Also signing the bond, as his security, was Jesse W. Young. This is good information, but it is the note that is filed with the loose bond that puts this into the "Wow!" category. On 14 May 1842, Delitha wrote a note to the county court stating that she wanted Watkins to be appointed her guardian because "I have neither Farther nor Mother living my age is about Sixteen." At the age of 14, minors were considered mature enough to choose their own guardian, but this note gives a more exact age and it states that both of her parents were deceased. The names witnessing her note are important, also. We know that Jesse W. Young was Watkins' security for the guardian bond, but who was Leven T. Olover?
When a minor married, a parent or guardian had to give consent for the license to be issued. If there were no living parents, or even if the father alone was deceased, a guardian was often appointed for that specific purpose. A check of Caldwell County marriages shows that on the same date the guardian bond was issued, Levin T. Oliver obtained a marriage bond to marry Miss Delitha Lemmen in Caldwell County. Ah ha! Leven was a principle player in this saga.
One record is often insufficient to get the complete picture so help yourself by checking every possible record.
