Byrnsville, or Tioronda, was a hamlet near the mouth of the Fishkill creek, about a mile south of Fishkill Landing, and contained the Tioronda Hat Works. In 1880 it had a population of two hundred and seventeen. The Hat Works occupied the site of an old cotton-mill at this place which failed before 1850. A grist and saw-mill were subsequently built on the site but torn down by Lewis Tompkins in 1878 when the Hat Works were erected. A little below these works is the former site of the Madam Brett grist-mill, for which this has been mistaken.<ref name=smith/>

Groveville derives its name from the extensive oak grove which formerly occupied the site. There was a grist mill at Groveville from a very early day, owned about 1820 by Samuel Upton, a Quaker. who acquired it from Abraham Dubois. Upton also erected on the opposite side of the race a stone building which he used as a fulling mill. Sometime after 1840, the property, was sold it to the Glenham Co., who converted it to a woolen mill, and did carding, spinning and weaving.<ref name=smith>{{Cite web|url=https://www.ebooksread.com/authors-eng/james-h-james-hadden-smith/history-of-duchess-county-new-york--with-illustrations-and-biographical-sketch-272/page-107-history-of-duchess-county-new-york--with-illustrations-and-biographical-sketch-272.shtml|title=Read the eBook History of Duchess county, New York : with illustrations and biographical sketches of some of its prominent men and pioneers by James H.
