Found this bit of info, and perhaps Philipse Hall has copies of the text.
On November 28, 1776, the same year that 56 Americans signed the Declaration of Independence, well over 200 colonial New Yorkers placed their signatures on a "Declaration of Dependence." One such signer was Frederick Philipse III, Lord of the vast Manor of Philipsburg and resident of the elegant mansion known today as Philipse Manor Hall. Philipse and his family later fled to England where he died in 1786. His land and his mansion were confiscated by the New York State Legislature and sold at public auction. By the 20th century, city growth threatened the Manor Hall's future until New York State acquired it in 1908. Today, Philipse Manor Hall serves as a museum of history, art, and architecture as well as host to community organizations and meetings.
Frederick Philipse III and his family lived in luxury, well-supported by rents from the many tenant farms on his property. But times were changing, and while others rebelled against Great Britain, Frederick III defended the Crown. His Loyalist beliefs were so strong that General George Washington ordered him arrested in 1776. Philipse and his family later fled to British-occupied New York City and then to England, where the last "Lord of the Manor," broken in spirit and health, died in 1786. His land and his mansion were confiscated by the New York State Legislature and sold at public auction.
Philipse Manor Hall passed through the hands of several owners and was even purchased for use as the village hall. By the 20th century, city growth threatened the Manor Hall's future until New York State acquired it in 1908. Today, Philipse Manor Hall serves as a museum of history, art, and architecture as well as host to community organizations and meetings. Highlights of the Hall include its 18th century, high style Georgian architecture and a 1750's papier mache Rococo ceiling.
