The Patagonian Bones is a 2015 Argentine film written and directed by Ricardo Preve.^[1] With a telefilm format, The Patagonian Bones is based on the true-life story of Catherine Roberts, the first Welsh woman to die in Patagonia in 1865, and on the 20-year work of three Argentine scientists to identify her remains.^[2][3] The film had a successful run at international festivals, winning awards and nominations.

A group of Welsh colonists decides to emigrate to Argentina's Patagonia region in 1865. Among them is a woman called Catherine Roberts, her husband, and her three children. On board the sailing ship Mimosa they arrive at present day Puerto Madryn, Chubut Province, Argentina on July 28, 1865. Catherine dies on August 21 and is buried near the coast, but all trace of her is lost until 1995 when some bones are discovered by chance. Argentine scientists Silvia Dahinten, Julieta Gomez Otero, and Fernando Coronato work for 20 years to determine if the remains found are those of Catherine. In 2015, with the arrival in Puerto Madryn of a Welsh descendant of Catherine, and new scientific research techniques, the scientists are able to confirm that the bones found in 1995 are those of Catherine.

Preve came in contact with the story while visiting the city of Puerto Madryn in 2012. He met Dahinten, Gomez Otero and Coronato who were working on the project as researchers of the National Patagonic Center (CENPAT), a dependency of the CONICET. When the remains were found in 1995, also recovered were a gold wedding band (with no initials on it), a mother of pearl button, and a coffin made with European wood. The researchers suspected that the remains were those of Catherine Roberts, but it was not possible to be certain about this until the DNA found in the bones could be compared to that of a descendant of Catherine. Preve and his production team travelled to Wales and interviewed Nia Owen Ritchie, a descendant of Catherine. Then they returned to Argentina with Nia and filmed the extraction of a genetic sample from Nia, which determined that there was a 99% chance that the remains found in 1995 were those of Catherine. After the film was completed, in 2015 the documentary was broadcast on Argentina Public Television.^[4]

The film was also screened in theaters in Wales^[5] and is available in many countries on the online platforms Amazon Prime and YouTube.^[6] In 2020 the city of Puerto Madryn showed the film on the occasion of the 155th anniversary of the arrival of the Welsh settlers.^[7]
