The business of the Cunard Company, in its various branches, has from its origin been carried on in Glasgow by Messrs. G. & J. Burns; in Liverpool, by the energetic firm of Messrs. D. & C. MacIver; in Halifax, N.S., by Messrs. S. Cunard & Co.; and in New York, by Sir Edward Cunard, Bart. Mr. David MacIver died a few years after the formation of the Cunard line, Sir Samuel Cunard, Bart., and his son Sir Edward, died more recently; and James Burns and George Burns having retired several years before the death of the former, which took place in September last, the business devolved upon the two sons of George Burns--John Burns and James Cleland Burns, of Glasgow; Charles MacIver, of Liverpool; and William Cunard, formerly of Halifax, N.S., now of London, who remain the sole partners of this gigantic concern, which is still further extending its ramifications by the addition of a line of steamers between the Clyde and the West Indies. The subject of our memoir married, in 1822, the eldest daughter of the late Dr. Cleland of Glasgow, a man who may be said to have been the father of social and vital statistics in this country; for at the time he published his works, "Annals of Glasgow," and "Statistical Tables," we believe that Sweden was the only country that laid claim to the possession of regular statistics. Dr. Cleland was a member of the Institute of France, and other scientific bodies. By his wife, who is still alive, Mr. Burns has had seven children, of whom there only survive the two sons who are now at the head of the business in Glasgow. Mr. George Burns, soon after his retirement from business, purchased the estate of Wemyss Bay, where he now spends the greater part of his time. Mr. John Burns is possessor of the property of Castle Wemyss, where he resides; and Mr. James Cleland Burns lives at his property of Glenlee, near Hamilton.
