I am trying to trace a very distant relative. Harold McComas migrated to Canada circa 1910 with his Father William, and brothers William and Frederick. They were originally from Salford near Manchester in England .Due to health reasons the family sought a warmer climate and all but Harold McComas migrated to Australia and arrived in Sydney Australia in 1913.I understand that Harold married a native American woman from the Sioux tribe. Can anyone assist me with information on Harold or his descendants orat least somewhere to start looking for immigration or other records. Thanks.
