William Penn

329 years ago  (March 4, 1681) Charles II repays a debt owed to the Penn Family by making the following grant to the Quaker William Penn:

Doe give and Grant unto the said William Penn, his Heires and Assignes, all that Tract or Parte of Land in America, with all the Islands therein conteyned, as the same is bounded on the East by Delaware River, from twelve miles distance Northwards of New Castle Towne unto the three and fortieth degree of Northerne Latitude, if the said River doeth extende so farre Northwards; But if the said River shall not extend soe farre Northward, then by the said River soe farr as it doth extend; and from the head of the said River, the Easterne Bounds are to bee determined by a Meridian Line, to bee drawne from the head of the said River, unto the said three and fortieth Degree. The said Lands to extend westwards five degrees in longitude, to bee computed from the said Easterne Bounds

Excluding prior vague Colonial grants from the ing stretching to the "western sea" this was probably the first time that anyone ever felt compelled to write down property boundaries and transfer a claim of ownership to the land that would eventually be claimed by me.
