L'Enfant arrived in Georgetown on March 9, 1791, and began his work, from Suter's Fountain Inn [REF].
L'Enfant secured the lease of quarries at Wigginton Island and further southeast along Aquia Creek off the lower Potomac River southern bank in Virginia to supply well-regarded "Aquia Creek sandstone" for the foundation and later for the wall slabs and blocks of the "Congress House" in November 1791 [REF].
