Vice-Admiral Sir Charles George Frederick Knowles, 4th Baronet (14 March 1832 – 3 March 1917) was an officer of the Royal Navy, who saw service during the Second Burmese War and in command on the Niger expedition and quelling uprising at Santa Cruz, eventually rising to the rank of vice-admiral.

Family and early life
This family is descended from Charles Knollys, titular 4th Earl of Banbury temp James II. Knowles was born on 14 March 1832 at Vaynor Park, Berriew, Montgomeryshire, Wales, the son of Sir Francis Charles Knowles 3rd Baronet and his wife Emma Pocock, daughter of Sir George Pocock, 2nd Baronet. He was the fourth of his line since his great grandfather, Sir Charles Knowles, admiral, was created a baronet for purely naval services in 1765. His grandfather, Sir Charles Knowles, followed his own father's career, rising to Admiral, though his son, Knowles' father Sir Francis Charles Knowles, discarded a life in the service to devote himself to the pursuit of science, and succeeded in attaining to the blue ribbon of the scientific world - a fellowship of the Royal Society in 1830. On the maternal side also, Knowles had a very distinguished naval pedigree, for his mother was the granddaughter of Admiral Sir George Pocock, the victor of the Havanna, who had been shipmate with the first Sir Charles Knowles whilst midshipmen at the defeat of the Spanish fleet at Cape Pissaro 1718, commanded by his kinsman, Admiral Lord Torrington. It was into a century of general peace that the third admiral of his line was to pursue a more peaceful naval career than that of his forebears. With a fleet larger than any two rivals combined, there were to be no major battles fought, just localised military action buttressed by the Royal Navy.
