Dalrymple-Hamilton was the son of Col Hon. North de Coigny Dalrymple-Hamilton, MVO, of Bargany, Girvan, Ayrshire, and the grandson of the 10th Earl of Stair. He joined the Royal Navy in 1905 and served in World War I. Promoted to Captain in 1931, he was appointed Captain (Destroyers) for the 4th Destroyer Squadron in 1933 and Captain of the Royal Naval College, Dartmouth in 1936.
From 1939 to 1941 he commanded the battleship HMS Rodney and while in command he took part in the sinking of the German battleship Bismarck. He was appointed Admiral Commanding Iceland in 1941 and Naval Secretary in 1942. He became Commander of the 10th Cruiser Squadron and Second-in-Command of the Home Fleet in 1944 flying his flag in HMS Belfast in June 1944 during the D-Day landings at Normandy. A few months later commanded the escorts of several Arctic convoys as well as the British forces involved in the inconclusive Action of 28 January 1945. He went on to be Vice-Admiral Malta and Flag Officer, Central Mediterranean in April 1945.
Frederick Dalyrmple is descended from the 10th Earl of Stair. The Hon. North de Coigny Dalrymple-Hamilton, the Earl's second son is his father. His mother is Marcia Liddell, daughter of The Hon. Sir Adolphus Frederick Octavious Liddell and Frederica Elizabeth Lane Fox
He married Gwendolen Peek in 1918 (died 1974); they had one son and two daughters. Both had royal godparents: son North was a godson of Edward VIII and daughter Graeme Elizabeth was a goddaughter of Queen Elizabeth, the Queen Mother.
Their son Captain North Edward Frederick Dalrymple-Hamilton (1921-2014) followed his father into the Royal Navy and became executive officer of the Royal Yacht Britannia. 
Frederick and North Dalrymple-Hamilton are the only documented father and son who witnessed the sinking of the German battleship The Bismarck. Frederick Dalrymple-Hamilton, then a Captain, was the commanding officer aboard HMS Rodney while his son served as a gun director aboard HMS King George V. After the battle Frederick told his son: “You are lucky to have seen a show like that after only being in the Navy for 18 months — I’ve had to wait 35 years.” 
His and Gwendolen's grandson, North John Frederick, served as a Page of Honour to the Queen Mother.
