There is a good collection of photos on the Stolz family, and also the Zarth family who is related. That you are apparently not local, you could plan a visit well in advance so that the materiaks would be available for research.
Unfortunately I'm not close and wondering how I can fill out a form for the reseach
If you are located on the island you can stop by the museum and fill out a research request for the subject. The museum also has a research room that contains many documents available for public perusal.
