Hi,
Try looking up the living people via social media or do a Google search for them.
To locate where survivors were living when they died, your local public library can order newspapers on microfilm via inter-library loan,

You can also contact the Fort Worth Library,
www.fortworthtexas.gov/library/info/default.aspx?id=24852 and order copies of obits 1966-1993. Successful Searching!
