Jacob was the first in the family to be born in California in the rugged north coast outpost of American civilization in Humboldt. He would spend his entire life there helping his father establish the dairy industry and raising a large family.

The first notice of Jacob is at the age of 1 in his father's family when the census was taken for Rohnerville. And the next record for him is the June 21, 1867 Honor Roll for Rohnerville School which also honored his sister Mary Ann Showers.

Jacob married Laura Ellen Blanton on January 31, 1886 in Rohnerville, Humboldt, Ca. She was daughter of John H. Blanton, Sr. and Elizabeth Shepherd.

The photo detail to the tight must have been taken circa 1911 when the Rambler 63 was a new model and impressed the photographer enough to include it in the caption (misspelled the name Showoers).

Jacob was involved with a lawsuit concerning some public timber lands he had applied to buy in Oct. 1881 which William Friend later applied to buy in Dec. 1882. The local authorities initially ruled in favor of Friend, but Jacob appealed to Land Commissioner McFarland who ruled he had the prior claim and Friend's application was invalid. But then Friend appealed to Acting Interior Secretary M. L. Joslyn (in place of Secretary Henry Moore Teller) who reversed McFarland's decision on Nov. 24, 1884. He ruled that Jacob had bought the land not as a site to settle but to procure the timber, and he had failed to make any improvements on the land as required under the act of June 3, 1878 which was intended to provide inexpensive land for agriculture. So the decision was reversed and Commissioner McFarland was directed to recognize the claim of Friend ("Decisions of the Department of the Interior and General Land Office in Cases Relating to the Public Lands from July 1884, to June, 1885" - page 210).

Jacob inherited the family ranch on Elk River which continued as one of the leading dairy producers in the area, and he was the manager of the Elk River Creamery which processed the milk from the ranches in the valley (listed in the 1914-1915 directory Eureka and Humboldt County). The Creamery had been built in 1901 but it is not clear if he built it or it was one of the last acts of his father as reported in the March 31, 1901 edition of the "Times Standard" (page 24). The construction of the Elk River Creamery, in partnership with a Dennis Carlin, had been completed the week before and was "...already the scene of thriving activity. This creamery is one of the finest now in the county. Its situation is admirable, and the creamery itself is up to date in every particular. The concrete work, which consists of the foundation, the churn pillars, and the floors of the butter, churn, and engine rooms is a sample of excellent work by Charles Hull of Eureka. The creamery is completely ventilated. The fine engine and fixings were put in by Langforc Bros.."

Jacob is recorded as the lead plaintiff in a suit bought against Madaline M. Zanone who evidently agreed to pay 20% of the cost for construction of drains (apparently undertaken by land owners in the Elk River who often had to deal with flooding). She had refused to pay after construction, and an initial trial had ruled for Jacob and the other plaintiffs. She filed an appeal with the Court of Appeal, Third District where the case was heard and the verdict upheld for the plaintiffs on April 13, 1906 (Pacific Reporter, Vol. 85).

The 1930 census for Elk River shows Jacob, retired at age 71, as the head of his large family living on the ranch valued at $3,000. The group includes his wife Laura (written as Louise) 61, sons Oscar 37, Lloyd 36, Ora 34, Jim 30, Elmer 28, Mart 22, Francis 19, daughter Lucile 18, and grandson Eldred 11 (son of Lloyd).
