Hi Andrea, The Dunshee name was listed as E.S DUNSHEE ("photographist") as early as 1875 on 3 Tremont Row. In 1887 he was E.S. DUNSHEE & CO., same address. There were HILL photographers in Boston as early as 1887---C.G. HILL was at 363 Washington St., and HILL & HAZELTON at 24 Hanover St. Early photographers acquired and dropped partnerships as business dictated, and often sons and sometimes their widows took over upon their decease.
