The Archives has custody of the official manuscript records of Fairfax County, the home of founding fathers George Washington and George Mason. Cf. Official Records of the Colonial Period in Fairfax County.
The Circuit Court Archives contains original deeds, wills, court orders, summons, suit papers, and other documents recorded in the Fairfax Court since 1742. There are no records on meteorology especially pertinent, except a curious entry by the Clerk at the beginning of the 1772-1774 court orders which reads:
Memorandum: Be it remembered that on the eleventh day of June in the year one thousand seven hundred and seventy three it rain'd Hail'd snow'd and was very cold. (True by my Journal)
