Yonkin was born in Illinois on October 11, 1850, moving to Los Angeles in 1885 and starting a political career at the age of 35. He served as a deputy sheriff to John C. Cline and was later elected to as a constable for two terms.^[1] While serving as a constable, Yonkin was sued for $1,500 for allegedly attaching property from them to help satisfy another party.^[1][2] In July 1903, Yonkin was accused of a felony for prejudice against M. N. Melrose during his trial.^[3]

In 1906, Yonkin was elected to the Los Angeles City Council, succeeding Arthur D.

In 1917, Yonkin was elected to the California State Assembly for the 73rd district, beating Socialist George W. Downing and Democrat Harvey B. Dalton in the 1916 election.^[9] After serving a term, Yonkin was elected to the California State Assembly for the 38th district beating Independent Charles H. V. Lewis, who would later serve after Yonkin after Yonkin's term.^[4][10]

Yonkin was married to Anna M. Yonkin; they had two children. On February 9, 1941, Yonkin died at the age of 90 at his home in Historic South Central.^[11] Funeral services for Yonkin were held on February 12.^[4]
