Lily Verna Snyder married her brother-in-law's former employee in January, 1878. Until F. Jay Haynes death in 1921, she was not only a wife and confidant to her photographer husband and mother of the Haynes' three children, but also a photo colorist and retoucher, photographic assistant, and studio manager. After their marriage, Lily managed the Moorhead, Minn., studio while her husband devoted much of his time to photography along the Northern Pacific Railroad in the western U.S. territories and Yellowstone National Park. She later oversaw Fargo, ND, studio business and supervised the business while Frank travelled with the Studio Car and went to Yellowstone. When the family moved to St. Paul, Minn., the photography business had expanded to the point that FJH could hire assistants for the studio work and his wife's unpaid labor was unneeded. Lily Haynes was an active church worker and St. Paul hostess. She died at home in 1927.
