I am not 100% sure Liberty is buried in St. Mary's cemetery, St. Mary's, Hancock County, Illinois. St. Mary's is an unincorporated town near the Hancock County/McDonough County border. There is no gravestone in the cemetery for him and his wife unless it has sunk or something. I contacted the caretaker for the cemetery and was told the records were lost in a fire years ago. My aunt Marj and I got the date of 1898 from another aunt of mine. I have no idea where she got that from. I have not been able to find anything to corroborate it.
Liberty is my brick wall also because I can not find his parents and or siblings. All I know is that he had a sister (name unknown) who married a Clapsaddle. Also, I have never found proof as to the locations and dates of birth and marriage.
