Did you know my Great Aunt?

Hello, this is a long shot but...
I'm trying to find anyone who knew or has information about my great Aunt who lived in Lindenhurst.
Her name was Estella Walker and she lived in Bayview Ave east in 1960 and maybe after.
She was married to Harry Walker who died in 1960 and is buried in Long Island National Cemetery, Farmingdale.

Estella was born in England and emigrated to Brooklyn in 1929 when she was 26 to live with Harry. They both moved to Lindenhurst sometime between 1942 and 1949.

I have no record of them having any children or family and after Harry's death in 1960 I have no record of what happened to Estella.

Can you help or do you know any one who might be able to?
Many thanks!
