Are we having a thread on threads, what man told you about those three, does the etc, mean you don't know any more threads.
How about BA, BSW, BSP, BSG, ME, ANC, ANF, UST and the mickey mouse sizes, plus some in obscure pitches used on cycles, cameras and telescopes. Howard & Bulloughs back in the 1800's used a lot of their own pitches. Even found a funny pitch on a gun sight, I was asked to repair, had to set the lathe up, to make a tap of the correct pitch, then make a die from that, before I could carry out the repairs, .185 x 23 tpi.
What man or web site are going to use to identify the above.
Want to borrow some taps and dies, I have most of the above sizes, from 0 to 10 BA, and up to 3/8ths in the other pitches.
