their ancestral home of Dismal Downs in 1675. Hugh turned to the sea for a living and became a successful merchant. He obtained his own ship, the Golden Goose, and became known by the nickname "Seafoam". In 1753, Seafoam McDuck signed a contract with Swindle McSue to deliver a cargo of horseradish to Jamaica. But McSue sabotaged the Golden Goose and the ship sank before reaching Jamaica. Upon returning to Scotland, Seafoam McDuck learned that his contract with McSue contained fine print stating that if the shipment was not completed, McDuck would forfeit all his possessions to McSue. Seafoam escaped with nothing but the clothes on his back, a silver pocket watch, and the golden dentures in his mouth. It is later presumed that Seafoam was involved in the American Revolutionary War and died in 1776. His descendant Quagmire McDuck inherited the silver pocket watch. Seafoam McDuck first appears in The Horseradish Story (1953) by Carl Barks. His ghost makes a cameo appearance in the 2017 DuckTales series episode, "The Secret(s) of Castle McDuck". Modern McDucks (1st generation) Dingus McDuck "Dirty" Dingus McDuck, was Scrooge's paternal grandfather. He worked as a coal miner, married Molly Mallard, and had three sons – Angus, Fergus, and Jake. He appeared in Don Rosa's illustrated family tree, but has not appeared in any comic book stories. A 1960s story by Bob Gregory and Tony Strobl identifies Scrooge's grandfather as Titus McDuck. In the 2017 DuckTales series episode, "The Secret(s) of Castle McDuck", Dingus is revealed to have had an antagonistic relationship with his son, Fergus (not unlike that of the latter and his son, Scrooge). In fact, knowing he would seek out Simon McDuck's treasure, he left his son a note telling him to work hard and not accept hand-outs inside a hidden chamber underneath Castle McDuck. Molly Mallard Molly McDuck (née Mallard) was the wife of Dingus McDuck, Scrooge's paternal grandmother, and the mother of Angus, Fergus, and Jake McDuck. Her first and only appearance was in an illustrated family tree created by Don Rosa; she has not appeared in any stories. Coincidentally, her maiden name is the same as the title character of Darkwing Duck. Her ghost makes a cameo appearance in the 2017 DuckTales series' episode, "The Secret(s) of Castle McDuck!" Quagmire McDuck Quagmire McDuck was Dingus McDuck's brother and Scrooge McDuck's paternal great uncle. He inherited a silver watch from
