Willing to try and assist your search. Based on military date from you, his birth was between 1930 and 1940. Lucian Harold Martin Jr, son of namesake and Nina Bilberry fit that criteria. Lucian Jr wed Eileen Ethel Levens, 27 Mar 1967 in Randall County. They had Mark Ray, Matthew Volney, and Nina Nancy. If one of these siblings is your parent then I'm on the right track? Slightly bewildered! Your grandfather should still be alive 'cause I've found no Texas Death Record or listing in Social Security Death Index? I did find a public telephone listing for L H Martin in Lubbock. Hope that's the "right person" and he's receptive to making/renewing your acquaintance?
