Allan MacDonald (b. c1825), Margaret MacDonald (née Morrison b. c1828), Christina MacDonald (b. c1852) & Catherine Morrison (b. c1829) emigrated together from Nth Uist (Langass?) to South Australia in 1853 on the ship HMS Hercules. I would appreciate any further information about Allan & Margaret's family histories on Nth Uist. Thanks, Michael Smithson.
