I sent you a private message, but I also wanted to post here in case it helps anyone else. From your mention of the NJ memorial, I was able to locate their page on him along with his picture. Also, his bio mentioned his siblings and that was enough for me to trace his ancestry back three generations to his great-grandparents Henry Koonce & Elizabeth Ellis of Jackson County, Florida. I wrote a blog post about it at http://tinyurl.com/lfgv57
I am not related, but I have enjoyed finding his family. Thanks for the information.
