I was checking out this website www.archive.org and came across this video of a Barber shaving a new born baby's head with a straight razor www.archive.org/details/7la2etNabil I also came across a lot of barbers books from the late 1800s to the turn of the century that can be downloaded for free. There is a lot of good historical information on this website for just about anything, check it out let me know what you think.
