Talk on landscape history Saturday

As local officials gear up to celebrate “Historic Waltham Month” in July, a genealogist and Waltham Historical Society board member will deliver a talk about how the region’s landscape was shaped 350 years ago. The lecture by Marie Daly, from 10 a.m. to noon Saturday at the Lyman Estate, 185 Lyman St., draws on her research of land in Waltham, from 17th-century farms to 20th-century subdivisions, and offers tips on how to trace parcels through such sources as family histories, deeds, tax records, and Town Meeting minutes. The admission fee for “Great Dividends: Researching Land in a New England Community’’ is $10, or $5 for members of the event’s sponsors, the Waltham Land Trust and Historic New England.
