I have a lot of information on the Casper Ehlert that died on the USS Arizona. He was my grandfather's uncle, and my family has a treasure trove of documentation about him. I have not scanned much of it, as the documents are still with my grandfather in Wisconsin and I now live in California, but feel free to email me directly and we can connect on the phone sometime. My email address is firstname.lastname@example.org
Looking forward to talking with you!
