Thank you for trying to help. Charles Henry Smith's parents were Henry Smith and Lucretia Smith (nee Toomey).
Lucretia may also be Louisa or Louise on some records. Lucretia is a Roman/Latin name for Louisa. My Mum and i will be visiting Australia next year and we are tracing the descendants on behalf of my grandmother, who is nearly 82 years of age and is one of Charles' nieces.
