That is an interesting vignette for mine,
it shows the clipper Mimosa at anchor, with every sail
Of the thousands of ship vignettes, I have never seen one so.
I was born in Somerset which originally was "South Wales"
The story is very similar to the Utopian settlement
in Paraguay of "New Australia"
The Mimosa was a clipper ship best known for carrying the first Welsh emigrants to South America in 1865.
By the time Mimosa made the voyage she was already past her prime, having been built in 1853 at Hall's shipyard in Aberdeen. She had not been designed to carry passengers, but had been converted for the purpose. The cost of fitting provisioning and chartering the ship was £2,500 and the passengers paid £12 per adult or £6 per child for the journey. 
Before the voyage the emigrants assembled at various points, not always their places of origin, to prepare for the journey, including Aberdare, Birkenhead and Mountain Ash.
Mimosa sailed from Liverpool, England on May 28, 1865 to Patagonia, South America with a group of about 153 passengers with Captain George Pepperell and a crew of 18. Thomas Greene, an Irishman from Kildare, had been appointed as ship's surgeon. They landed on July 28, 1865 and named their landing site Porth Madryn. They were met by Edwyn Cynrig Roberts and Lewis Jones who had already arrived in Patagonia in June 1865 to prepare for the arrival of the main body of settlers.
Their aim was to establish a Welsh colony which would preserve the Welsh language and culture. The proposed site for the colony was in the Chubut River valley. On September 15, 1865 the first town in the Chubut colony was named Rawson, and the settlers went on to build the settlements at Gaiman and Trelew.
The exact number of emigrants who sailed out to Patagonia on the Mimosa remains uncertain. Although one of the original settlers, Richard Jones (Berwyn), maintained a register of births, marriages and deaths for many years, most of these original records were lost in the great flood in the Chubut Valley in 1899.
In 1875 the Argentine government granted the Welsh settlers ownership of the land which encouraged hundreds of others from Wales to join the colony.
The colony became known, in Welsh, as Y Wladfa.
