Looking for Robert Kemp Who Married Carol Myers and Ann Brewer

Looking for information and parents of Robert KEMP b. abt 1807 Middlesex, England who married Carol MYERS and then married Ann BREWER.

Robert, Carol and daughter Phoebe emigrated to Australia aboard the "Thetis" in 1841, arriving in Victoria, Australia.

Once in Australia, Robert married Ann BREWER (also emigrated onboard Thetis) and this started my line of the KEMP's.

Kind regards,
Andrew
