A group of Welsh settlers decided to emigrate to Argentine Patagonia in 1865. Among them, a woman named Catherine Roberts, her husband, and their three children. Aboard the ship Mimosa they arrived at the current Puerto Madryn, Chubut, on July 28, 1865. Catherine died on August 21 and was buried near the coast, but her traces were lost until 1995 when some bones were discovered by chance. Argentine scientists Silvia Dahinten, Julieta Gómez Otero and Fernando Coronato have been working for twenty years to determine if the remains found are those of Catherine. In 2015, the arrival in Puerto Madryn of a Welsh descendant of Catherine, and new scientific advances, allow us to confirm that the bones found in 1995 are those of Catherine.
