[3] He was appointed by Congress as a physician and surgeon general of the Northern Department of the Continental Army in 1780, and served until the close of the war.

[3] In 1790, State Senator Anthony Hoffman died, and Tillotson was elected to fill the vacancy.

[7] Tillotson purchased from Isaac Van Etten the southerly lot forming part of the lands which had been granted in 1688 by Governor Dongan to Gerrit Aertsen and others.

It was bounded on the south and west by the Hudson River and on the east by the stream known as Landsmans Kill, which also formed the westerly boundary of the Beekman patent.

This plateau, between the two streams, with extensive views of the Catskill mountains and Hudson river, became known as Linwood Hill.

Dr. Tillotson also obtained at this time another part of the Beekman lands, twenty-nine acres of woodland lying east of Fallsburgh Creek, where two beautiful waterfalls bring it to the river level.
