Sarah Ann Curtis was a ninth generation American. She was descended solely from Puritan stock. Her American ancestors emigrated from the British Isles between 1630 and about 1650 into Massachusetts and Connecticut.
The first American ancestor of Sarah Ann Curtis was Jehu Burr (1596 to 1657), who came to America in 1630 with the Winthrop Fleet.
[Jehu Burr was the 2nd great grandfather of Aaron Burr (1756 to 1836), the third vice president of the United States. Sarah Ann Curtis was the 5th great granddaughter of Jehu Burr. Thus, she was a third cousin three times removed from Aaron Burr.]
