1859 Rooms on Main Street, Penn Yan, New York.
J. C. Mills was recorded in an announcement on March 30, 1859 in the Penn Yan Democrat (Penn-Yan, New York). Photographs, Daguerreotypes, &c. We happened into Mr. Mills’ Photograph and Daguerrean Gallery (entrance on the west side of Main St., at the first stairs south of Runns’ Bookstore) the other day. While there we were shown some very nice specimens of pictures, Photographs, Ambrotypes, Melainotypes, &c, some of which equal in execution any we have ever seen. Mr. Mills is preparing to take Photographs in a new style, which have proven very acceptable to those who have seen them. The general mode of procedure, we believe, is about the same, but the effect given to the picture is not a little improved. Mr. M. has a good sky-light, and all arrangements complete for taking excellent pictures.
J. C. Mills is listed in Craig’s Daguerreian Registry as being active in Penn Yan, New York in 1859 without a business address.
