There was a degree of notoriety attatched to the family as William's brother Thomas b.1852, who had served on the schooners Koh-I-Noor , Cecil Brindley and the steamer Electra, was hanged at Carmarthen for the murder of his sister-in-law Mary Davies nee Hughes at the cottage now known as Nerella. Her husband James Davies had often sailed with his brother-in-law Thomas on the S.S. Electra. There had been an ongoing feud between the two sisters Mary and Catherine Richards nee Hughes, over the cottage. The sisters had been left an equal share of the property; and whilst childless Mary and her husband enjoyed its use, Catherine and Thomas and their three children had to rent Sandon Villa, Upper Borth. There is a vast amount of reportage around the murder and subsequent trial which can be found in the National Library of Wales' newspapers on line. The perpetrator was shunned by the rest of his family except for his wife and children. Perhaps it was this event that persuaded Captain William Richards to build a third house called Maelgwyn at Pengarn, so he could distance himself somewhat from the scandal. Currently little is known about David b.1841, John b.1848 or Evan b.1855, only that the latter is recorded as being at sea during the 1881 census.
Anne, wife of Captain William Richards, had a sister who also married a mariner; Captain Griffiths. He had been born in Dolau of farming stock. He left home at the age of fourteen to work with the vicar of Pennal. The young man’s intelligence aligned with a keen interest in seafaring so impressed his employer that he sent him to study navigation with the polymath Cranogwen, which was the Bardic name of Sarah Jane Rees 1839-1916 who lived at Llangrannog. Sarah was a precocious child and at a young age persuaded her captain father to take her on his voyages as opposed to home duties and sewing. She became a competant mariner and skilled navigator under her father's tutelage, supplemented later by attending navigation school in London. This was only one facet of her prodigious talent. Young Griffiths gained his master mariner certificate in Dublin and went on to command the Mexican and the Roebuck of Wisbech. On one of his voyages, after a two year absence, it was presumed that the ship and the crew were lost. No sooner had the insurance been paid out, and other matters concluded, than the long overdue ship returned causing great consternation. Not least of all to his wife, and apparently after this event she persuaded Captain Griffiths to give up seafaring and to concentrate on agricultural matters at Dolclettwr Farm Treddol.
