My original biography of frank came from information I found on a book about the centennial of Oregon. What the book left out was what he did before he got to Oregon. Frank had 3 wives. First Isabelle Flett he abandoned her with 3 small children and ran off to New Mexico with her sister Christine. She had two children by Frank. He abandoned her and went on to marry Sarah Adams and had two children with her.

In 1869 he moved to Minneapolis, Minnesota, where he was in the employ of the government as engineer and
surveyor, continuing in that position for 12 years. He then moved to Nebraska, where he was engaged in surveying until 1888, at which time he went to Spokane, Washington, and there for some time followed his profession of surveying. He then took up his abode in Pendleton, Oregon, and continued to reside there until 1891, when he moved to Portland and there accepted a position as chief clerk in the United States surveyor general 's office. He continued in that position for a period of 2 years, after which time a change in the political administration necessitated his discontinuance in the office. Two years later he was appointed inspector of government surveys by the commissioner of the United States land office in Washington and in 1904 he settled at North Bend, Coos County, Oregon, where he has since continued to reside. He built one of the first residences in the southern part of that town and was the owner of one of the very fine homes in North Bend. He was the city engineer of North Bend and was also engaged in the real-estate business. He was for four years employed by the Mexican government in engineering work and while he lived in the east served for 2 1/2 years in the United States Navy. Mr. Brigham supported the Republican Party and was a member of the Benevolent Protective Order of Elks and also of the United Artisans

One of Richard's Great Grand Daughters disputes the claim that Frank spent any time in the Navy..
