Thomson Family Farm
Why it's listed
Thomson Family Farm occupies about ninety acres near the head of Thomson Hollow, in the Catskill Mountain region of Delaware County, New York. John Thomson, a Scottish immigrant, acquired the land around 1820 and began clearing it. Over roughly a century the farm grew from a subsistence operation into a large commercial dairy farm. Two buildings survive: a one and one-half story wood-frame farmhouse built about 1835-40 and a three-story dairy barn from about 1881 with stalls for twenty-five cattle. Foundations mark a horse barn, wood shop and sheep barn, and traces remain of a mill pond, sluiceways and a spring-fed water line. Stone walls, spruce-lined driveway, fields and wooded hillsides complete the landscape. The farm is documented by the diaries of James Thomson and the memoirs of his grandson Ralph Thomson. It was listed for its role in settlement, agriculture and the Scottish farming community around New Kingston.
Significance in brief: The nomination argues that the farm documents the growth of a Catskill farm from a subsistence homestead into a large commercial dairy operation over about a century. It is tied to Scottish settlement of the New Kingston area. The surviving landscape, buildings and ruins, together with detailed family diaries and memoirs, illustrate farm life and agricultural practice.

What listing means for this property
This is a historic district. Buildings within its boundary are either contributing (they add to the district's significance) or non-contributing. Owners of contributing income-producing buildings can claim the 20% federal rehabilitation tax credit; homeowners should look at state credits. National Register districts impose no design review by themselves; a local historic district ordinance, if one exists, does (the difference explained).
