Hi Tammy, my father was on the tennessee during the pearl harbor attack and fought many ships battles throughout the pacific. His name is Edward Earl Wise. He was a boatswains mate aboard ship and is still alive at 86 years old. I cant promise you that he would have known your grandfather but if you give me your email address I will forward it to him so he can contact you. You can write to me at edwise1180@msn.com. My father belongs to the pearl harbor survivors and knows several men from that ship that are still alive. Get in touch with me...maybe I can help you. best regards, Ed Wise
