Daniel Haydn Mainwaring was born on 28 June 1902 to coal miner Edward Mainwaring, and Mary Mainwaring, in Felinfoel, Llanelly.

In the 1921 Census, Daniel is listed as an out-of-work collier employed by Great Mountain Ltd, living at Brynglas, Llanelly Road, near Felinfoel. Daniel was likely on strike due to the ‘coal crisis’ of 1921. The crisis was ignited by the government’s decision to reprivatise Britain’s coal mines, which had been nationalised during the First World War. Many miners, like Daniel, went on strike throughout the 1920s in protest against the lower wages that would come with privatisation.

Daniel Haydn Mainwaring married Sarah Elizabeth Thomas on 5 April 1923, aged 20. They had three children together, Mair, Alun, and Harry, who sadly died in infancy.

Sadly, Sarah passed away suddenly in 1928 at the young age of 26, from kidney disease.

Following this tragedy, and in light of the turmoil affecting the British coal industry, Daniel, now aged 27, decided to leave his children with his sister and immigrate to the USA for a new life. He travelled from South Wales down to Southampton with his friend Evans ‘Jack’ Griffiths, where they boarded the RMS Berengaria on 9 November 1929.

The passenger lists held at The National Archives show that Jack and Daniel sailed to Ellis Island, New York. ‘U.S.A.’ is listed in the column ‘Country for Intended Future Permanent Residence’. They then travelled onwards to Scranton, Pennsylvania, a coal and steel city, and a major hub for Welsh migration.

Daniel married Edna Mae Ball, another migrant from the UK, in 1933. They had three children together: Jean, Margaret (known as Peg) and Barbara. Daniel spent his working life in Scranton, as a Mining Superintendent.

It was not until 1975, 46 years since leaving on the RMS Berengaria, that Daniel was reunited with his daughter Mair and son Alun, when he came back to the UK for the first time. Daniel died just one year later on 13 August 1976 in Taylor, Pennsylvania, USA, at the age of 74. Daniel’s daughter from his second marriage, Peg, and her husband, made the trip across the Atlantic throughout the 1980s and 1990s, visiting her half brother and sister, and spending time with Daniel’s grandchildren and great-grandchildren.
