ericstreet on Family Tree Circles

I am researching my Street family in South Africa. My family tree mainly consists of the following families: Scully, Kemper, Street and Gunn. My GG Grandfather, Samuel Street married a Mary Crespin North. My G Grandfather, Sidney Alan Street married a Mary Gunn and my Grandfather, Henry Forbes Street married Evelyn Kemper. My father, Douglas Street married Pamela Scully. My research has become difficult finding ancestors of Samuel Street and Mary Crespin North and hope someone can help.
