CATHERINE ALEXANDER DUER (1755-1826)
Catherine Alexander was born to William Alexander, known as Lord Stirling, and Sarah Livingston of New York. As a Livingston, her mother was a member of the prominent Hudson Valley family, and a sister of Philip Livingston, a signer of the Declaration of Independence. Alexander, a major general in the American Revolution, was a self-proclaimed Scottish earl (although his title was never recognized officially), and for this reason Catherine gained the nickname “Lady Kitty.”
Lady Kitty grew up in the company of celebrated generals, revolutionaries, and their families. On several occasions, George Washington himself visited the Alexander home in Basking Ridge, New Jersey, and gave Lady Kitty away at her 1779 wedding to Colonel William Duer (1747-1799). Her new husband, with whom Kitty would have seven children, became a leading businessman and stockbroker, and his wealth made it possible for his wife to host extravagant parties. The Rev. Manasseh Cutler, after attending a dinner party in 1787 at the Duer household in New York City, observed:
Lady Kitty, for so she is called…is a fine woman, though not a beauty, very sociable, and with most accomplished manners. She performed the honors of the table most gracefully, was constantly attended by two servants in livery, and insisted on performing the whole herself. Colonel Duer…lives in the style of a nobleman. I presume he had not less than fifteen different sorts of wine at dinner, and after the cloth was removed, besides most excellent bottled cider, porter, and several other kinds of strong beer.
Directly related to Sarah Livingston Jay (the two women were first cousins), and more distantly to Alexander Hamilton, Lady Kitty and Colonel Duer were on the guest lists for New York City’s most prestigious social gatherings, including George Washington’s first Inauguration Ball. She also helped outfit one of New York City’s finest mansions for use by the president and his famiy. In a letter dated April 30, 1789, Sally Franklin Robinson writes:
I went the morning before the General’s arrival to look it [the President’s house]. The house really did honour to my Aunt [Mrs. Samuel Osgood] and Lady Kitty; they spared no pains nor expense in it…
In addition to her roles as hostess, socialite, and even interior decorator, Kitty Duer also participated in family financial matters. Surviving correspondence indicates that she occasionally handled bank transactions for her husband: in one letter she notes borrowing 1,100 dollars on Duer’s behalf, and also explains that she will have to pay for some expenses while he is away. Duer (who had, while secretary of the Board of Treasury during the Revolution, helped Robert Morris finance the war) borrowed extensively on credit that he could not repay, and when the stock market bubble burst in the spring of 1792, he was left with a debt of about $3,000,000—more than $40,000,000 today. Arrested and thrown into debtors’ prison that March, where he would die in 1799, Duer left Lady Kitty with virtually nothing. His actions as a speculator set off the Panic of 1792, the first real economic crash for the new nation.
With her life of luxury ended, Lady Kitty and her eight children moved from their grand home on Broadway to a small brick house on Chambers Street, where she took in boarders. With her subsequent marriage to merchant William Neilson, several more children joined the household. Despite her straitened circumstances, Lady Kitty did not fall out of contact with members of the Republican Court.
