JulieTideman on Family Tree Circles

Robert MARSHALL was born in 1843 (or 1842) emigrated to New Zealand in 1866 and married Margaret STEWART. Robert was one of 40 Irish settlers who came to NZ on the ship "Mary Shepherd" to purchase land in North Auckland. He arrived with his cousin William Day LESLIE and Mary Ann LESLIE. I have the details in New Zealand but no idea of his parents or brothers and sisters. Any help appreciated, I've hit a huge brick wall. Thanks
