Charlie - Congrats on your success in finding the information on your dad's family in Williamson County and now knowing that his mother was named Minnie Azilee Ratliff. If you haven't already, you should check in the courthouse and see if you can locate death certificate for her as that may give you the name of her parents, etc. etc. Also check the newspaper office in Liberty Hill and see if they have an obit for her. My Ratliff's came to Williamson County from Crawford County, Arkansas. My great great grandmother was named Sarah Jane Marrs (she married William Perry Ratliff) and from the information I have, the Marrs family has some relation to Sam Houston. I have Ratliff family members who are buried in Florence as well as in a Ratliff family cemetery which is on private property about 5 miles south of Florence on Highway 195. Hope you can locate more concrete information on your Ratliff family and if you think I can be of further assistance, please don't hesitate to contact me. Good Luck on your Search.
