I found a death cert. for a Richard Eugene Lakey in Jasper Co. Tx on 2-24-1976. SEE ATTACH'd His wife was the informant on the document and her name is listed as Thelma Laverne Lakey. This is different than the name you listed for your grandmother. I have several LAKEY's in my family info, but not my direct line. Several aunts and uncles and even a second marriage or two. I would be glad to see if I can help but need to see how this man fits your grandparents.
Also, HOPSON is one of my direct lines. I will gladly share what I can and help if I can.
