Hi there,
My name's Nicky Swaby. There's a good chance we may be related...My father is Neville Swaby, whose siblings are the ones you mentioned. I spent time with my uncle Roy and his family in Mandeville when I was a young girl. I met my grandmother Elsa once before she passed away. My mother knew my aunt Navlyn and another brother (who was a police inspector) who also passed away.
Hope you see this message...
