Welsh

And here I might add that Catlin found the following singular resemblances between the Mandan tongue and the Welsh:

Scholars trace Lugh’s name to the Proto-Indo-European root *lewgh-, meaning “to bind by oath.” This aligns with Old Irish *luige* and Welsh llw, both signifying “oath” or “vow.” The older theory linking the name to “light” or “flashing” (leuk-) faces phonological objections and receives less support today.

Cantre'r Gwaelod (also spelled Cantref Gwaelod or Cantref y Gwaelod, meaning "The Lowland Hundred" in Welsh) is a legendary sunken kingdom from Welsh mythology, often called the "Welsh Atlantis." It is said to have been a fertile, low-lying land in what is now Cardigan Bay (west Wales), stretching roughly between Ramsey Island (Ynys Dewi) and Bardsey Island (Ynys Enlli), with its capital at Caer Wyddno.

Related or parallel tales include the submergence of Llys Helig (Helig ap Glanawg's kingdom near the Conwy estuary) and the land of Teithi Hen, suggesting the motif of drowned lowlands was widespread in Welsh lore.

The story developed between the late 15th and 17th centuries, drawing from older oral traditions and possibly influenced by the Welsh legend of Cantre'r Gwaelod (a sunken kingdom).

The name Kêr Ys means "low city" in Breton (kêr = city/fort, like Welsh caer; ys/is = low).

His father, Scotch-Welsh descent, was a pioneer preacher among the Disciples of Christ.

Similar spring rites existed in other cultures, such as the Germanic Walpurgis Night and the Welsh Calan Mai.

The name "Morgan" is likely derived from Old Welsh or Breton, meaning "born of the sea", linking her to water deities.

Welsh, Danish, and Breton also retain remnants of base-20 counting.

If we could imagine Highland Scotch, Welsh, Cornish, and Irish populations emigrating en masse from England in later times, and carrying to their new lands the civilization of England, with peculiar languages not English, we would have a state of things probably more like the migrations which took place from Atlantis.

And one of the most curious facts is that the ancient Britons, as the Welsh do to-day, call a pilot llywydd (lode).

The Ethiopic word gaber, to make, to do, and the Arabic word jabara, to make strong, becomes the Welsh word goberu, to work, to operate, the Latin operor, and the English operate.

The Arabic word abara signifies to prick, to sting; we see this root in the Welsh bar, a summit, and pâr, a spear, and per, a spit; whence our word spear.

The Arabic sanna, to be old, reappears in the Latin senex, the Welsh hen, and our senile.

The Arabic baraka, to bend the knee, to fall on the breast, is probably the Saxon brecau, the Danish bräkke, the Swedish bräcka, Welsh bregu, and our word to break.

The Arabic baraka also signifies to rain violently; and from this we get the Saxon rœgn, to rain, Dutch regen, to rain, Cimbric rœkia, rain, Welsh rheg, rain.

The Chaldee word braic, a branch, is the Irish braic or raigh, an arm, the Welsh braic, the Latin brachium, and the English brace, something which supports like an arm.

From the Arabic walada and Ethiopian walad, to beget, to bring forth, we get the Welsh llawd, a shooting out; and hence our word lad.

Now, after the fall of the great empire, Egupt, her people migrated westward, hundreds of thousands of them, and they settled in western Uropa, where these people married with the aborigines. Their offspring were called Druids, Picts, Gales (Galic), Wales (Welsh), Galls (Gauls), and Yohans (Johns), all of which are Eguptian names, preserved to this day.

Welsh:The lake of Llion burst, flooding all lands.

The god of the Welsh triads, "Hu the mighty," is found in the Hu-nap-bu, the hero-god of the Quiches; in Hu-napu, a hero-god; and in Hu-hu-nap-hu, in Hu-ncam, in Hu-nbatz, semi-divine heroes of the Quiches.

We are reminded, in this Boiling Lake of Dominica, of the Welsh legend of the eruption of the Llyn-llion, "the Lake of Waves," which "inundated the whole country." On the top of a mountain in the county of Kerry, Ireland, called Mangerton, there is a deep lake known as Poulle-i-feron, which signifies Hell-hole; it frequently overflows, and rolls down the mountain in frightful torrents.

And here I might add that Catlin found the following singular resemblances between the Mandan tongue and the Welsh:

The meaning of these enigmas could only be hoped from deciphering the chaos of barbaric monuments of the Welsh middle age; but meanwhile we cannot doubt that the Cymri possessed an indigenous tradition of the Deluge."

Three catastrophes are mentioned in the Welsh traditions.

This is consistent with geological evidence and aligns with Welsh and Greek legends of successive deluges.
