Robert Dalzell (died 1878)

Colonel the Honourable Robert Alexander George Dalzell, CB, Knight of the Order of the Medjidie (19 August 1816 - 19 October 1878) was a British aristocrat and soldier.

Dalzell was the youngest son of Lieutenant-General Robert Alexander Dalzell, 6th Earl of Carnwath, and Andulusia Browne. He had 3 older brothers who each survived their father to be successively Earls of Carnwath.

On 27 August 1846 he married Sarah Bushby Harris, daughter of Captain John Harris, RN, of Eldon House, Ontario, Canada. Together they had the following children: Dalzell died on 19 October 1878 aged 62. If he had survived his elder brother, Harry Dalzell, 10th Earl of Carnwath, he would have himself succeeded as Earl of Carnwath, the title instead passing to his eldest son, Robert Dalzell. To recognise this, his other children were raised to the rank of children of an Earl by Royal Warrant of Precedence in 1889.
