The teenage girl is too old to be their daughter (given Stephen's affluence, it would be surprising if they didn't have at least one live-in servant).

Listed next to Elijah HILL, whose wife, Lucy, will become Stephen's next wife.  William BERRY (æ 30, b. OH), presumed widower of our subject's daughter, is unmarried and living with four other unmarried working men in Portland, Washington [now Multnomah] Co., OR (p. 129B).

"Susanna" should be Lucina.  Henry, Franklin, and Clarissa HILL are Lucina's children from her prior marriage (Virginia is Henry's wife).  Elizabeth is apparently George's wife and Charles their son.

Our subjects have managed to get enumerated twice, probably because they have a residence in town and a residence at the penitentiary.  Getting enumerated twice is unusual, but not unheard of, and each time I've seen it happen, the differences between the records always gives me pause.

I wonder if this is a third wife or if "Ruba" may just be Lucina's nickname.  Wm. W. is Stephen's son by Lucina, so his mother would not be born in RI.

A "memorial" published in the 4 Dec 1900 issue of the Portland Oregonian:

General Stephen Coffin, prominently identified with the early history of Portland, was born in Maine in 1807 and came across the plains in 1847. He located at Oregon City, and by frugality and enterprise amassed a considerable amount of money, and in 1849 purchased a half interest in the Portland land claim, associating himself with D.H. Lownsdale.  The partnership was later joined by Colonel W.W. Chapman.  General Coffin was a leader in promoting the initial enterprises of Portland.  With his partners he resolved to operate an opposition steamship line between this city and San Francisco.  The Pacific Mail had established its river terminus at St. Helens.  With his partners and others he purchased for $18,000 the steamship Gold Hunter, which proved a very unfortunate investment.  The ship was run off to Central America through the treachery of agents and sold for debt, and a large balance was charged up to the stockholders.  General Coffin was the prime mover in the project of building the wagon road to Tualatin Plains, which cut so important a figure in the development of Portland's business.  He took a leading part in the organization, 1860, of the People's Transportation Company, and was vice-president and manager of the corporation, which for many years controlled the transpiration on the Willamette River.  For some time it carried on sharp competition with the Oregon Steam Navigation Company on the Columbia River.  About 1866 he took a large interest in the Oregon Iron Works, which was destroyed by fire and netted him a loss of about $40,000.  He took an active part in promoting the Oregon central road, west side.  He built by contract about 20 bridges.  He was a member of and a large contributor to the Patrons of Husbandry in Oregon, and with others organized the order into a business known as the Northwestern Storage & Shipping Company.  He was associated with various business enterprises, and took a very active and prominent part in matters for the general welfare of the public.  He donated to the City of Portland its public levee and gave largely to churches and schools.  The first church and school bell in the city was purchased by General Coffin.  When the Yakima Indian War broke out he was the first man to move for the defense of the settlers.  He provided a steamboat at his own expense, with provisions and blankets, to transport troops for the defense of the settlers.  In 1863 Governor Gibbs made Mr. Coffin Brigadier-General of the Oregon militia.  He is altogether one of the best-remembered and highest-esteemed of the original town proprietors.  He died at Dayton, Yamhill County, March 16, 1882."
