Welsh settlers took their musical culture to America as well as their mining skills
An expert on Welsh migration to America is embarking on a prestigious lecture tour of the United States.
Dr Bill Jones from Cardiff University will visit major institutions including Harvard and Campbell Universities.
He'll also speak at the opening of an exhibition at the Scranton Anthracite Museum in Pennsylvania largely based on his research into Welsh migration.
The area was the subject of Dr Jones's first book, Wales in America: Scranton and the Welsh 1860-1920.
Dr Bill Jones is an expert in the history of 19th Century Welsh migration
Dr Jones said: "I am particularly looking forward to speaking at Scranton because the area was formerly an important coal, iron and steel making centre.
"So it is unsurprising that it attracted migrants and expertise from the Welsh coalfields and became the largest Welsh community in the USA in the late nineteenth and early twentieth centuries."
Also on display at the Scranton Museum will be a touring exhibition on the Welsh in America organised by New York office of the Welsh Assembly Government, to which Dr Jones contributed.
During his visit to the US, Dr Jones will be giving papers on his recent research into Welsh American letters at the Department of Celtic Languages and Literatures, Harvard University, and at Campbell University, North Carolina.
Welsh settlers in Pennsylvania were proud of their heritage
He will be speaking about the Welsh American writer and women's rights campaigner Margaret Evans Roberts (1833-1921) at Great Plains Welsh Heritage Centre, Wymore, Nebraska.
Dr Jones will also address meetings of the St David's Welsh Societies in Nebraska and Minneapolis where he will talk informally about various aspects of his research into emigration from Wales.
Professor Peter Coss, head of the school of History and Archaeology at Cardiff, said: "Bill Jones is a remarkable and prolific historian.
"His research reveals the dramatic role that Welsh communities played in moulding modern America.
"As such it has great significance for reinforcing long-standing cultural and collaborative links between Cardiff University and Wales, more broadly, and academic schools, heritage institutions and communities across the United States."
Dr Jones's tour runs from 11 to 27 March.
