The village, which (according to Baring) then consisted of five farmsteads, was renamed Heinse or Hönze in 1553, and around 1600 (according to Gesenius) also Haensen, and according to Lampadius Erben, Hainsen. Dr. jur. Jakobus Lampadius (Jakob Lampe 1593–1649), the later Vice-Chancellor of the Duchy of Brunswick-Lüneburg, was born here. As a young scholar, he was appointed tutor to the Crown Prince by Duke Friedrich-Ulrich and, at the age of 28, was appointed professor of constitutional law at the University of Helmstedt. Even as a young man, he was entrusted with important state affairs. He acquired farmsteads in Heinsen and one in Ahrenfeld and combined them into one estate. For his great services to the duchy, Duke Ulrich, by deed dated October 6, 1626, released him from all burdens and taxes on his estate in Heinsen and granted him hunting, fishing, and brewing rights, as well as the right to build a mill and administer the lower court within his district. These rights also applied to his descendants.
Lampadius represented the entire House of Welf at the Imperial Diet of Regensburg and, with great success, the duchy as an envoy at the Peace Congress (Thirty Years' War) in Münster from 1643 onward. Chancellor Hardenberg purchased the estate, which remained in the family after his death, and had a magnificent manor house and similar outbuildings built in 1724.
