Kiliaen van Rensselaer (fourth patroon)

When Kiliaen came of age, he travelled to Albany, and received naturalization papers from the English colonial government.

[2] Upon the death of his uncle, Jeremias Van Rensselaer, in 1674, he became patroon of Rensselaerswyck.

Young Kiliaen's aunt, the widow of Jeremias, Maria Van Rensselaer, and her brother, Stephanus Van Cortlandt served in an advisory capacity.

[3] While he was Patroon, the patroonship changed to an English lordship, and so was the first Lord of Rensselaerwyck.

[5] Kiliaen died without issue at Watervliet, Albany county, about February 22, 1687.

A black, circular seal with a notched, outer border. The center contains a shield or crest with a crown atop it. In the shield is a beaver. Surrounding the shield are the words "SIGILLVM NOVI BELGII".
On a white background, three black glyphs appear, aligned vertically and connected along one vertical line which shares at least one line within each glyph except for the bottom one. On top is the number 4, written with the top closed. Its horizontal line extends to the right and is intercepted by a vertical line making a cross. Its vertical line continues below to form the vertical line of a letter R. That line continues down to connect to a letter W, which is written like two letters V crossing each other. The vertical line connects to this intersection point.
