It is also presented as an important example of mid-Georgian architecture with later additions. It retains integrity of design, materials, workmanship and setting, and meets Criteria A and C.","narrative":"Built around 1760 at 125 Dascomb Road in Andover, this clapboard house was constructed by Jacob Johnson, a blacksmith who kept his shop on the property after marrying in 1758. It is a 2½-story Georgian building with a gable roof, center chimney, five-bay facade and center entrance. Around 1830-36 a Greek Revival renovation added corner blocks at the windows and a modest entry vestibule with sidelights. The house passed to Johnson's son and grandson, both named Osgood, the younger of whom became headmaster of Phillips Academy. In 1832 it went to Jacob Dascomb, a deacon of the West Parish Church, who sold it in 1852 after financial losses. Later owners included sea captain Llewellyn Murch, who added a piazza that has since been removed. The house was listed for its connection to the early growth of southern Andover, its ties to educational and religious figures, and its well-preserved mid-Georgian design with later additions.","period_of_significance":null,"architect_builder":"Jacob Johnson (original owner and builder)","architectural_style":"Georgian, with Greek Revival renovation ca. 1830-36","criteria":["A","C"],"status_note":"Present use is residential, the same as its original use.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:11:57.032866-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/opastorage/live/47/7899/63789947/content/electronic-records/rg-079/NPS_MA/82004826.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/82004826/7d565cdecb-800.webp","url_1600":"https://nationalhistoricalregister.com/media/82004826/7d565cdecb-1600.webp","licence":"CC BY-SA 4.0","author":"User:Magicpiano","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:AndoverMA_DascombHouse.jpg\" rel=\"noopener\">User:Magicpiano</a>, <a href=\"https://creativecommons.org/licenses/by-sa/4.0\" rel=\"license noopener\">CC BY-SA 4.0</a>, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:AndoverMA_DascombHouse.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/63789947","wikipedia":"https://en.wikipedia.org/wiki/Dascomb_House","wikidata":"https://www.wikidata.org/wiki/Q14715447"},"indexable":true,"url":"https://nationalhistoricalregister.com/massachusetts/essex-county/dascomb-house-82004826/"}
