about.
in researching genealogy, i found the dulles brothers ancestors were tied both to the dupont family & to the brown family (brown brothers) back to the 18th century. I learned this entirely from my own research putting biographical information from various sources together:

In 1819 Joseph H. Dulles married Margaret Welsh of Philadelphia, whose roots were in the Brandywine Valley of Pennsylvania and Delaware. Her father, John Welsh, is sometimes described as Delaware-born, sometimes as English-born.
What's certain is that he started his career with the shipping merchant Joseph Russell, then with financier Robert Ralston (b. 1761), of Philadelphia and Little Brandywine.
Coincidentally, Ralston was a founder of the Second Bank of the US (with financier Stephen Girard and others) -- the bank Jackson fought, whose first President was JH Dulles' brother-in-law Langdon Cheves.
After leaving Ralston's employ, Welsh founded J&W Welsh with his brother William.
The Welsh firm had two renumerative lines of business. One was the West Indies trade, which meant trading the slaves or slave goods of the Caribbean plantation economy.
The other was shipping cheap labor from Ireland to the Brandywine Valley, often as an agent for the DuPont family.
DuPONT
The French aristocrat Éleuthère Irénée du Pont de Nemours came to the US in 1799 in flight from the guillotines of the French revolution.
By 1802 he'd established a gunpowder works on Brandywine Creek in Delaware, not too far from the milling enterprises of John Welsh's wife's Maris clan. Government contracts tripled DuPont's sales by his second year in business.
The DuPont connection was helpful when John Welsh wanted to start his own bank:
"...organized in August 1803 at Welsh's countinghouse with a capitalization of $1 million...the bank was able to survive with the support of prominent customers like E.I.DuPont..."
Welsh's "Bank of Philadelphia" became the "Philadelphia National Bank," then "PNB," and is now "CoreStates," a bank holding company with 1996 assets of 45 billion dollars.
The DuPont connection became a family connection when Elizabeth Canby Bradford married Alexis Irenee DuPont, director of DuPont 1890-1904. Alexis (b. 1843) was the great-grandson of E.I. DuPont, and Elizabeth was the great-great granddaughter of J&W Welsh partner Samuel Canby (b. 1751).
Canby was also the first cousin once removed of Margaret Welsh's mother, Jemima Maris.
MARIS/BROWN BROTHERS
The Marises, neighbors of the DuPonts, were among the earliest settlers of the Brandywine Valley and owned much of its valuable river front, where they established grist and sawmills. They were extensively intermarried with other "first" families of the area, like the Canbys and Shipleys.
Thus Joseph Shipley Jr. (b. 1795), another cousin of Jemima Maris, came to work for Joseph Welsh at J&W Welsh. Welsh sent Shipley to Liverpool as his business agent.
Liverpool had been the European hub of the slave trade until 1807, when England abolished slavery. But even afterward, the city's commerce revolved around cotton and slave goods & the businesses and shipping routes forged through the slave trade.
In Liverpool Shipley met William Brown (b. 1784), son of Alexander Brown (1764), the Irish linen merchant who immigrated to Baltimore (another slave trading hub) in 1800 and founded Alex Brown & Sons, the beginning of the Brown Brothers financial dynasty.
Brown & Shipley was established in Liverpool in 1825; its initial business was cotton trading (& reportedly, financing slave ships as well).
Brown & Shipley is said to have moved the major portion of US cotton traded to England at the time of the Civil War.
JH Welsh provided part of Brown-Shipley's start-up capital, and kept an interest in the business on that basis.
The Brown connection, like the DuPont connection, continued through the generations.
John Welsh's g-grandson William S. Stokes (b. 1893), for example, married Ruth Coxe, the great granddaughter of Brown Brothers partner Alexander Brown (1815), grandson of founder Alexander Brown (1764).
Alex (1815) Brown's wife Catherine Neilson was daughter of Abraham Schuyler Neilson (1792).
A.S. Neilson's neice, Cornelia Neilson (1814) married Orlando Harriman (1813), whose grandson William Averell Harriman (1891) would become the "Harriman" in "Brown Brothers, Harriman".
John Welsh's son John Jr. (1805) was Minister to England for President Rutherford Hayes("Minister to St. James"). His son John Lowber Welsh was with the family firm J&W Welsh & Co, by then associated with Drexel & Co.
JL Welsh reorganized the Pennsylvania-Reading Railroad with John C. Bullitt & JP Morgan, representing a "Syndicate" of 7 investors including: John Garrett (Shipley family relative), Samuel Shipley (Shipley family), & Henry DuPont...
