Unfortunately I don't have access to Ancestry. On the entry showing the 3 Redman's there was nothing for another passenger, so one has to assume he might have been born in South Africa. Will have a look and see if I can pick up a baptism. Did see that there was a death for an Osborne Huggins in 1931 in the Cape, and also one for a Osborne Ernest Huggins in 1961 in the Transvaal. Did not look at them, but will do if you are interested.
