Dickie Duck's grandfather might be (or possibly was) an anthropomorphic duck.
Description[]
Goldie O'Gilt is known to have had an anonymous daughter. However, with whom is unknown. Some people theorize that said daughter was in fact the illegitimate daughter of Goldie and Scrooge McDuck. However, others argue that Goldie was probably married with an unknown man at some point between Scrooge's departure from the Klondike (in 1899) and the two's reunion in 1953.
Behind the scenes[]
If he does indeed exist as a separate person from Scrooge McDuck, his existence could first be inferred from Dickie Duck's first appearance in the 1966 comic The Miner's Granddaughter.
