Dutch monarchs family tree The following is a family tree for the Princes of Orange, a line which culminated in the Dutch monarchy with the accession of Prince William VI to the newly created throne of the Netherlands in 1815. Dates given are those of birth and death; for Princes of Orange (shown in bold), the intermediate date is the date of accession to the Princedom. By virtue of his marriage to Mary II of England, Prince William III, himself a grandson of Charles I of England, became King of England 1689–1702 (jointly with Mary II until her death in 1694) following the overthrow of his uncle and father-in-law James II of England in the Glorious Revolution. The family lineage is of note as John William Friso is the most recent common ancestor of all the current monarchs of Europe.
Golondrina point Golondrina points (formerly Plainview Golondrina) are lanceolate spear or dart projectile points, of medium size, dated to the transitional Paleo-Indian Period, between 9000–7000 BP. Golondrina points were attached on split-stem hafts and may have served to bring down medium-sized animals such as deer, as well as functioning as butchering knives. Distribution is widespread throughout most of Texas, and points have also been discovered in Arkansas and Mexico. The concentration of Golondrina specimens is highest across the South Texas Plains, where the point is the most prevalent of Paleo-Indian types and defines a distinctive cultural pattern for the region. The Golondrina point is so named for its flared basal corners ("ears"), which resemble a swallow's ("golondrina" in Spanish) split tail. Classification of Golondrina can be difficult because of its similarity to other types, particularly the Plainview point, to which it was originally thought to be related.
