On May 20th, 1777, a bill for “for dividing the County of Albemarle” was passed after its third reading. After the passage, Speaker of the House George Wytheville ordered then Delegate Thomas Jefferson to carry a bill to the Virginia Senate.
The Midland Virginian reported that:
The new county was cut from the mother county by a line running from the most western point in the line of Louisa County directly to the lower edge of Scott’s Ferry, on the Fluvanna, now the James River …. embracing all of Albemarle Countt lying eastward of that line, including the islands in the river … to the Goochland County line, a few hundred yards beyond the town of Columbia …
