After arriving in Oregon, Wilcox took a job teaching in Portland, Oregon, in 1847 and became the first teacher in that city.[1][3][4] Later that year George Abernethy, the governor of the Provisional Government, appointed Wilcox as a county judge for Twality (now Washington) County.[1] Also that year he was elected to the Provisional Legislature.[5] The next year he was elected again and served in the final sessions of the provisional government in 1848 and 1849, including time as the speaker of the assembly.[6]
In 1850 after Oregon had become a United States territory, Wilcox was elected to the Oregon House of Representatives of the Territorial Legislature, replacing David Hill and served as speaker of the body.[7] The following year he returned representing what had become Washington County, but was not selected as speaker.[8] In 1853 he returned to the legislature serving as president of the upper chamber Council.[9]
From 1856 until 1858 Ralph Wilcox served as a registrar for the U. S. Land Office in Oregon City, and then as county judge in Washington County from 1858 to 1862.[1] Wilcox was also elected Oregon City mayor during this time.[4] In 1862 he returned to state politics and was elected as a representative to the Oregon House of Representatives as a Republican from Washington County.[10] Also, from 1862 to 1863 he was the school superintendent for Washington County.[11] During the American Civil War he was surgeon-general for Oregon’s militia, but no Oregon companies saw action in the war due to the distance to the fronts.[3] Then from 1865 to 1877 he was a clerk for the United States District Court for the District of Oregon in Portland.[1]
