Let's start here:
David Burke was born on 5 Dec 1914. He died in July 1974, and his last Social Security benefit was sent to Lafayette, Lafayette, Louisiana. His Social Security card was issued in Texas before 1951.("United States Social Security Death Index," database, FamilySearch (https://familysearch.org/ark:/61903/1:1:JTMX-FJ7 : accessed 8 June 2016), David Burke, Jul 1974; citing U.S. Social Security Administration, Death Master File, database (Alexandria, Virginia: National Technical Information Service, ongoing).)
FindAGrave gives his full name as David Henry Burke. He was buried at Indian Bayou Methodist Church, Indian Bayou, Vermilion Parish, LA.(FindAGravef.com; Created by: Leslie Burke; Record added: May 15, 2012; Find A Grave Memorial# 90192870)
Online (unsourced) family trees show that he married twice: Eva istre (1915-2000) m. 12 Dec 1931 Lafayette Parish; and to Mary Katheryn Huckins (1899-?). The 1940 US Census shows Mary K. Burke to be 22, 3 years younger than David.
Could Karen Marina Anderson be his third wife?
