The Salt family originally lived in Brooklyn, NY but moved to Bath, NY in the 1840s. William Salt married Jane Dodge of Brooklyn and the couple had nine children: William Salt, Jr., Mary, John, Elinor, Caroline, Phoebe, Jennie (possibly Jane), Dannie, Sarah, and Wellington.

William Salt, Sr. was a carpenter. Jane Dodge Salt had at least two sisters, Elinor and Sarah, and a brother, Titus Dodge. Elinor Dodge married Oliver Hicks and had a son Oliver. After her husband died, she lived with her mother, Jane Dodge, in Brooklyn. A cousin, Elinor Gustin, apparently lived in Pennsylvania. The family was Baptist.

William Salt, Jr., was the oldest child of William and Jane Salt. He was born in Brooklyn on 19 September 1837. When the family moved to Bath, he attended school for a time before leaving to work in his father's shop and continued to study on his own. At age 18, he began studying law and teaching school. In 1859, he converted to the Episcopal Church and decided to join the ministry, later receiving an offer to teach at a parish school in Van Buren, Arkansas. He arrived at this school in 1860, and remained there after the outbreak of the Civil War, unable to return to New York before travel was halted. After the school at which he was teaching, located within an army fort, was broken up, Salt entered the Theological Seminary at Camden, South Carolina. He and the other students at the seminary were later drafted into the Confederate Army, and he served for almost three years in the Marion Artillery. Towards the end of the war, he and another soldier made the journey north on foot, working at a farm for a time on the way.

After his return to Bath in July 1865, Salt worked for his father for a time before teaching at the Academy at Bath. Questioning his faith in the Episcopal Church, he investigated the Roman Catholic Church and was baptized in that faith on 12 October 1867 at St. Ann's Church in New York City, NY. He then entered the seminary at Seton Hall College before being sent by Bishop Bayley to study at the American College at Rome in 1870. Suffering ill health, he returned to Seton Hall and was ordained a priest 3 June 1871. Salt was appointed Professor of Logic, filled various chairs, was Director of the Seminary and Treasurer of the College, and was made Vicar General of the Diocese of Newark by Bishop Wigger. In 1881 he resigned as Treasurer but continued to teach and direct the Seminary until the late 1880s. He died on 7 October 1890.

Mary Salt, sometimes called Mollie by her sisters, married Burchard Platt in approximately 1880 and had a son, Roger. They lived in Bath. Burchard Platt died in 1905.

John Salt, born approximately 1839 (Drake account), worked in the naval shipyards in New York during the Civil War and then enlisted in the Union Army, a corporal in the 173rd NY Volunteers. He kept a diary during the war, and was killed in action during the assault on Port Hudson, Louisiana in 1863 (Drake account).

Elinor Salt was a teacher.

Caroline Salt, also called Cadeline, Carrie, and Caddie, may also have been a teacher.

Dannie Salt apparently married and had a daughter named Lizzie.
