We are taking a trip out to Liberty this weekend. I can attempt to see if it is available. I know William Jewel College Curry Library is supposed to have the Liberty Tribune Archived. I am going to make some phone calls in the next day or two. Do you have a death date of this person? If you need information about this ancestor, the Clay County Archives is a great place to contact. They charge $10 per surname search. Here is the link to their website and how to contact them:
