Shaun Grenan runs the Zouave Data Base website, and has the history of the 72nd posted there. I believe the correct URL for the homepage is at the link I have posted. It is a Tripod site, so may be hard for you to access. If so, feel free to email me and I can put you in touch with Shaun directly.
Below is a quote from the page in question as well:
