The summer cottage at 10 Pettipaug Avenue in the Borough of Fenwick was built in 1886 by William H. Bulkeley and was originally located at the site of the cottage of the cottage at 9 Pettipaug Avenue. William H. Bulkeley, (1840-1902) the brother of Morgan G. Bulkeley, is described in the Illustrated Popular Biography of Connecticut (1891):
General Bulkeley was born in East Haddam, March 2, 1840. Seven years later, his father, the late Hon. Eliphalet A. Bulkeley, established his residence in Hartford, and remained here until his death a few years ago. The young man was educated in the district and high schools of Hartford, principal T. W. T. Curtis being one of his instructors. He left the high school before graduation, with an admirable record for scholarship and application, and entered an old and leading dry-goods establishment here as a clerk. In March, 1857, he went to Brooklyn, N. Y., and engaged in the same business with H. P. Morgan & Co. Afterwards he entered the dry-goods trade for himself, and conducted a successful business for six years on Fulton Street, Brooklyn. In 1868 he returned to Hartford and organized the Kellogg & Bulkeley Company, lithographers, of which he has since been the president. He was for several years vice-president of the Aetna Life Insurance Company, and is at present a member of its board of directors. He is also a director or otherwise officially connected with a number of the banking, insurance, and other corporations of Hartford. In 1878 he purchased the “Bee Hive,” a famous dry-goods establishment, which he has since managed with great success, it being the chief secular object of his attention.
[. . .] General Bulkeley was elected to the office of Lieutenant Governor of Connecticut on the ticket with Governor Bigelow, and served through 1881 and 1882 with credit. [. . .] General Bulkeley has a creditable war record, having been one of the first to respond to the call for troops after the attack on Fort Sumter. He was a member of the Brooklyn City Guard, G company, Thirteenth regiment, N. Y. N. G., and advanced to the front with his command, April 19, 1861. The organization was in service for four months. In 1862 he organized Company G, of the Fifty-sixth regiment, N. Y. N. G., and was elected captain. He was with his command through the Pennsylvania crisis of 1863, being in General “Baldy” Smith’s division. The regiment was ordered home during the New York draft riots, after which it was disbanded, its term of service having expired.
Before his death, William Bulkeley sold his cottage to his brother Morgan who sold it in 1905 to Lucius Barbour, who moved it to its current site to make way for his own larger cottage.
