Queenie is the name of one of the main characters in Small Island by Andrea Levy. Here's a passage explaining how she was named:
I was christened Victoria Buxton. My mother had wanted me to be christened Queenie but the vicar had said, "No, Mrs Buxton, I'm afraid Queenie is a common name."
"Common!" my mother had replied. "How can it be common? It's a queen's name." The vicar had then given an impromptu sermon which my mother, father and their gathered guests had to listen to as they stood round the stone font in our bleak local church. The vicar went on at length about monarchs having proper names like Edward, George, Elizabeth while everyone, dressed in their pinching church-best shoes began to shift from foot to foot and stifle yawns behind their scrubbed hands. "Take our late queen," the vicar finally explained, "her name, Mrs Buxton, was not queen but Victoria."
So that was how - one thundery August day in a church near Mansfield, dressed in a handed down white-starched christening gown that wouldn't do up at the neck - I, the first born child of Wilfred and Lillie Buxton, came to be christened Victoria yet called forever Queenie.
