My great grandfather was married at age 20 in Brisbane Australia in 1875. He was born in Fyvie and some time between 1871 and 1875 he emigrated to Australia. I am unsure when he changed his name from William Strachan Beattie or why. He was listed in the 1871 census as a tailor's apprentice and in the Brisbane census as a tailor. I cannot find records of passage under either name.
