'The Barnum Family, 1517-1904' calls him Pell Barnum. Some sources call him Sallou Pell Barnum. From the Commemorative Biographical Record of Fairfield County, Connecticut (published 1899) comes the following:
Sallu Pell Barnum. Forty or fifty years ago the name of Barnum was well known to this part of Connecticut, if not to the State generally. Newtown has ever doted not a little on its commanding and beautiful town site. Its location and surroundings have made it an ideal summer resort, and its well-appointed hotels have not been the least attractive to summer visitors. Less than a decade ago the late William J. Dick, after a successful term of twenty-five years as the proprietor of the well-known and popular "Dick House," retired. His predecessor at the same stand for years was the gentleman whose name opens this sketch. Every one in that day knew "Pell" Barnum as the genial landlord in Newtown village. Mr. Barnum was born September 2, 1808, and October 5, 1831 married Laura Fairchild, born November 24, 1811. Their children were: Catharine J., born January 8, 1834 in Danbury; David Beach, born February 21, 1837 in Newtown and Sarah Frances, born May 14, 1845 in Newtown. It appears that in and about the year 1854 Mr. Barnum was town clerk. Sallu P. Barnum died July 26, 1872, in his sixty-fourth year; his wife passed away April 15, 1861, aged forty-nine years.
His gravestone reads: Barnum, Sallu P., died July 26, 1872, age 63 yrs. 10 mos.
