Looking for Charles and Charlotte March from Nth Uist IN Scotland

Charlotte MARCH was Charlotte MCVICAR and she came to South Australia on the Neptune and later to Melbourne on the Hercules 1853 with her parents Doonald and Mary MCVICAR. I do not know how Charles MARCH came to Australia but he married Charlotte MCVICAR at Bathurst in 1871 They settled near Carcoar NSW. Their daughter Elsie March married James Felix LANG in 1910. James and Elsie were my paternal grandparents
