Possibilities:

(1) Africa to USA with admixture in USA plus (2) Africa to Caribbean with admixture there followed by Caribbean to USA.

(1) Slavery era plus (2) post-Civil War era admixture enhanced by hypodescent rules and small size of African American population relative to white population in much of the USA.

as illustrated by figures in comment #3,(1) a pre-Independence plus (2) a pre-1808 ban surge.

The history of slavery in the US is that it began in the 17th century, but had its real growth in the early 18th century. The importation of slaves was banned in 1808 and the first decade of the 19th century saw a spike in importation:

Date Amount
1620-1700 21,000
1701-1760 189,000
1761-1770 63,000
1771-1790 56,000
1791-1800 79,000
1801-1810 124,000
1810-1865 51,000
Total 597,000

The years after 1808 until 1861, saw a rapid expansion of cotton plantations across the frontier south. Most of the slaves who labored there came from the eastern seaboard, particularly places like Virginia that were less suitable for plantation agriculture.

I have a notion of when the first pulse is (I’m figuring when the Melungeons, Redbones and Black Dutch and We-Sorts all sort of generally emerged from the historical murk), no clue as to the second pulse.

So we know that the pulses came before 1865, within the slavery period?
