Does Anybody Know More Info About Granville Lovett of KY

He's suppose to be my great great grandfather... even though my great grandmother never took his last name, he is her father. I only found out a few years ago but recently, I just started to get interested in family trees more. My great grandmother's name is Laura Bell Smith Gadd. She never took the Lovett name but her father is listed as Granville Lovett. Her mother is Mary Jane Smith. They later married after Laura and her brother were born. These two were raised by their Smith grandparents. So, if you have more info on where he is buried and where he is born and if he has more family and if they had more children after marriage, etc. I really would appreciate it. Thanks!
