Sorry I won't be much help! Philly Boxing History does not even seem to list him as one of their boxers although boxrec confirms that his residence was Philadelphia....birth place not listed????
The only info I have at all is from an old ticket stub My Pop-Pop had. He was a few years before my time so I have no information on him....My Pop-Pop had a stub from his fight w/ a Freddie Jackson back in 62'...looking into it Williams won by 5th round KO at the blue horizon, but outside of a blurb that mentions it in the next days paper....I am drawing blanks!
Good luck..why the interest????
