Does anyone know the approximate coversion rate of the English Pound circa 1800-1810? The typical rent for the Kayadrosseras patent was about 15-to-20 cents per acre. In one will I find a list of rents due given in pounds. Were I to know an approximate conversion, i could guess the amount of land being leased. j John F.
