If your grandfather is alive, ask him. If your grandfather is deceased, his birth certificate or death certificate may have the names. If you know where he lived as a child, you may be able to find him on a census record from around that time and see who his parents were. If they were church goers, there may also be some church records that would have this information.
That is interesting actually. The "S" is his middle name that his parents gave him. They did that in order to please his grandfathers who had names that began with "S".
