Felix Sumner Knyvett JP was the Founding H of the Chapter of Felicity No 58.

Born in 1839 to an armigerous family, he was a banker and later JP for his home county of Hertfordshire.

An initiate of the Lodge of Felicity in 1871, he was a Grand Steward in 1876, Master of No 58 in 1878, and later Junior Grand Deacon. He was Sword Bearer for Supreme Grand Chapter. He also founded the Felix Lodge No 1494 in 1874 along with six other brothers, but he was the only one named Felix. He joined Grand Stewards’ Lodge in 1877, and rose to be Master of that Lodge, an honour shared with two of his fellow Chapter founders, Charles Smith and Sir William Crump.

He was a member of the Conservative Club and the Kent Archaeological Society.

He died in 1906.
