Morfa Bychan, is renowned as the home of David Owen, an 18th-century blind harpist and composer.
He died at the age of 29 in 1741, and tradition has
it that as he lay on his death bed he called for his harp and composed the air Dafydd y Garreg Wen.

In order to finance the construction and repairs to the Cob, William Madocks let out his own house in Tremadog.
His first tenant was the poet Percy Bysshe Shelley, who antagonised locals by criticising their production of sheep for consumption, and by running up debts with local merchants.
Shelley made a hasty departure after an alleged attempt on his life by a nocturnal intruder, without paying his rent or contributing to the fund established to support Madocks.
During his tenancy, Shelley had written Queen Mab.

The Spooner family contributed a major amount towards the development of railways in the area over a period of more than 70 years in the 19th century.
