Sheffield married Miss Harriet P. Browne, daughter of Richard and Julia Browne of Providence, Rhode Island.
 This marriage produced one child, a son, Lucius T. Sheffield (May 28, 1854 – September 20, 1901).
Lucius Sheffield grew up in New London, Connecticut, and attended Norwich Free Academy.
Lucius followed his father into dentistry and dental surgery.
Lucius attended Harvard Medical School and graduated from Harvard's American Academy of Dental Medicine in 1878, see Figure 3.
After graduation, from 1878 to 1879, Lucius traveled to Paris, France, to study and work in dentistry and dental surgery.

Lucius was in Paris watching artists prepare their paint palettes when he realized the collapsible tubes they used to squeeze paint onto palettes could be used to squeeze his father's toothpaste onto a toothbrush in a sanitary manner.
