The house of Dr. Frederick Gilnack, at 19 Elm Street in Rockville (Vernon), constructed in 1890, is a quite late example of a Second Empire house. The mansard roof had been popular some decades before, but the house’s Eastlake style ornamentation places the it stylistically in the later nineteenth century. Dr. Gilnack was born in Saxony in Germany in 1844. His family came to America when he was ten and settled in Glastonbury. He was honored by Dr. Eli P. Flint in Proceedings of the Connecticut State Medical Society (1917), who gave an account of his life:
He was graduated from the College of Physicians and Surgeons, the School of Medicine of Columbia University, New York, March 14, 1867, and only three months later, in June, he located in Rockville, Connecticut, for the practice of his profession, which he continued there successfully, for forty-five years, until failing health obliged him to give it up.
He was especially successful as an obstetrician, and the loss of sleep and other exacting requirements which that class of practice necessitates, so lowered his vitality mentally and physically that he became unable to perform the duties of his profession for fiveyears, until an attack of epidemic influenza proved quickly fatal [in 1917].
