George Edward Cokayne FSA (29 April 1825 – 6 August 1911) was an English genealogist and long-serving herald at the College of Arms in London, who eventually rose to the rank of Clarenceux King of Arms.

On 15 August 1873, he changed his surname by Royal Licence to Cokayne (such changes were frequently made to meet the terms of bequests from childless relatives, often in the maternal line, who wished to see their name and arms continue).

[1] He matriculated from Exeter College, Oxford on 6 June 1844, and graduated BA in 1848 and MA in 1852.

[2] He was admitted a student of Lincoln's Inn on 16 January 1850, and was called to the bar on 30 April 1853.

[3] One of his sons, Brien, became Governor of the Bank of England from 1918 to 1920 and was ennobled in 1920 as Baron Cullen of Ashbourne.
