The reference B 495 probably refers to Probate Records Book B, Page 495. This would be in the Caldwell County records in the courthouse in Lockhart. In general, Texas Probate Records should have original as well as file copies of his will (if he had one), inventory and final disposition of personal and real estate, records of any law suits regarding the probate, if any, description of real estate locations, etc. You would probably have to go in person to the courthouse (or pay someone) to access the records and make copies. The clerks usually do not search for or make copies for researchers (although a few counties will do so). They will usually allow you to go in the records room area and pull books from the shelf and read and make copies ($1 each).
