Here is a list of the persons who had property in the "compact" part of Providence, RI, in 1759.  Because of fire problems, a tax assessment was made against property owners in the city proper, to defray the cost of fire protection.   The tax assessors thus provided us a written list of who owned property and something of comparative value of real estate property held by various owners of property. 

The list of 223 properties assessed has been put by us into alphabetical order, for ease in finding the persons you are interested in, with a number following the person's name. The number after the person's name indicates the amount he was assessed.

Captain Joseph Bucklin 4th, and Jonathan Bucklin show up in this list.  Joseph was assessed 20 pounds, which put him in the top 25% , by property wealth, of the town citizens.

List of Persons Assessed in 1759, amounts assessed in English pounds (£).

The Upper 10% of persons were assessed over 30 £.
The  Upper Quartile were assessed over 18 £.
The Median person was assessed 10 £ .      
The Lower Quartile were assessed less than 6 £.

Thus you can have an understanding of the valuation of his property relative to the property held by others on the list. In short, the more he was assessed, the more his house or other buildings were worth.
