Va. Code § 41.1-2
In all suits, either at law or in equity, in which title to any land is derived or sought to be derived from Lord Fairfax, through Denny Martin Fairfax, it shall not be necessary in order to make out a chain of title, to prove the act of Parliament authorizing Denny Martin, the devisee of Lord Fairfax, to take the name of Fairfax, but the same shall be presumed and taken to be true to the same extent as if a properly authenticated copy of such act had been adduced in evidence.
The records, documents, and entries of land granted by the former lord proprietor of the Northern Neck, and of all land granted, or to be granted, by the Commonwealth, shall be in the keeping of the Librarian of Virginia in the Land Office in the City of Richmond.
