Does anyone know of a method of either locating or finding information
about transistors that were manufactured in 1972? I am specifically
interested in locating or finding info on two transistors; their codes
a 2N5809 and 2N9614. I can't seem to find any supplier that has them
so I am presuming they are no longer manufactured. Thanks for whatever
help you can give me.

The 2N9614 is mentioned in a patent as a PNP Transistor.
