Dan, I've been doing genealogy for a long time now.The method you used will get you names of people having the same names as potential family members, but is no more of value than using Switchboard.com to find the same thing.An obituary, of say Glenn might say he had a brother Elmer, but, are they the same people as your cousins?
Of all the people you list, only Elmer would match age criteria.In the Social Security Death Index, Elmer is listed as being born on 17 May 1917 and died in November 1981.His "last residence" is in Prineville, Crook Co, OR. --The Oregon Library has an ask-a-librarian system.http://www.oregonlibraries.net/http://www.oregonlibraries.net/ Give them his name, his date of death, and where he was died.
And JUDY, his name is Elmer JAMES, not JAM.The database only has so many character allowances, but I've pointed that out before.
Dan, what you need to do is find out exactly who you seek.First identify your parent, or grandparent that would be the sibling of the parent to these cousins.THEN, someone can find that person in the US Census and then find these children/your cousins, when and where they were born.
