My grannie was Arthur street (can't spell ehthur), mind you she was born 1916 so may be a bit older than you.
My Mother (born 1908, Married 1935) whose mother lived round the corner in the Dumbiedykes might have known her.
I only left the old Forbes Street in 1971. I have worked out that as a toddler I lived in the St Leonards police cells - more accurely where the cells are now!
