The memorial may have limited information for about 30 days, but you should be able to add a virtual flower, flag, etc to the site. There's also a spot where you can share stories/remembrances. It's free.
I'm very sorry to hear this sad news. Jerry and I were stationed together as young seamen in 1965 at NAVFAC Grand Turk. My deepest condolences to Yukie and to all of Jerry's family. IUSS has lost another great leader.
