John Warren Hinkley was a son of John Hinkley, and descended through six generations from Thomas Hinkley, the governor of Plymouth colony, in 1681, and whose ancestry traces back to John D. Hinkley, high sheriff of Staffordshire, England, in the reign of Edward III, Anno Domini 1327.
John Warren was born in the city of Albany, on the 31st day of March, 1804. He was a pupil at the Albany Academy in 1818, and began the study of medicine several years later in the office of Dr. Peter Wendell, and continued it under the direction of Dr. Peter Van OLinda. Having attended a course of medical lectures in Boston, he received a license from the Albany County Medical Society, in October, 1825, and at the same time united with the Society and served for several years as its Treasurer. He at once began business in his native city where he continued to reside during the whole of his life. The records of the Society bear witness to his regular attendance at its meetings for many years. Dr. Hinkley received the honorary degree of doctor of medicine from the regents of the university of the state of New York, in 1854. He quietly and unostentatiously pursued the practice of his profession for a period of thirty-six years, enjoying the respect and esteem of his professional brethren, while he neither courted their friendship or their confidence. He was diligent in his business, and faithful to those who intrusted themselves to his care.
Dr. Hinkley died of hydrothorax, on the 26th day of March, 1861, at the age of fifty-seven, receiving during his illness the attendance of his life-long sincere friend and preceptor, Dr. Van OLinda. At the period of his illness Dr. Hinkley was contemplating joining his family, who at the time of his death were in Europe, whither they had gone for the completion of the musical education of a favorite daughter, who possessed a talent for music with a voice of rare sweetness and power. Mademoiselle Hinkley made her first appearance as a cantatrice on the continent, and after her return to this country was received with great favor. She became Madam Susini, and was winning reputation as a prima donna when she died suddenly in the city of New York, in 1862, at the early age of twenty-two years.
