William Summerhays was recorded in one advertisement that was recorded in the Nantucket Inquire (Nantucket, Massachusetts) on May 4, 1858. The subscriber is now prepared to take those splendid Milleneotypes, which are far superior to anything yet discovered for lockets. He also continues to take the Ambrotypes, in a style unsurpassed. Persons wishing an imperishable picture of themselves or friends can obtain them at the most reasonable prices at the Saloon on Centre Street.
P. S.—The Subscriber will remain in Nantucket, and warrants every picture he puts up. Wm. Summerhays.
William Summerhays is recorded in other photographic directories as being active in Nantucket, Massachusetts in 1860.
