I can only reiterate the information in several trees - death 1974.
Death announcement Belfast Telegraph 3rd April 1974.
It would be worth checking out.
Death notice Belfast Telegraph 3rd April 1974 reads:
“Parke – April 3, 1974 (suddenly) at home, JOSEPH BEATTY PARKE, D.Sc, Ashford, Sandy Hill, Drumbeg, Belfast. Loved husband of Dorothy and dear daddy of XXXX. House and funeral private. No flowers please.”
Child's name removed as she might be alive. Can send it by pm if you want it.
