Culture of Somerset County 1794

I have been using  ''The Federal Direct Tax of Somerset County, Maryland, Abstracted and edited by Tom Reedy, Willow Bend Books, Westminster, Maryland, 1999.

I have several questions to help me understand the culture of 1794.

What role did a slave superintendent have in this period?

What and how were the following buildings used:

Corn Stack

Milk house

Meat house

Smoke house

Corn house

Can I find descriptions of the following construction methods:

pole building

wood framed windows

log, sawed log, hewed log

Kitchen round poles

Cider house round logs

windows plain finished

logs covered with slabs

What good maps might I use for this period?

Maps that include the property names like Harris Chance, Harris Adventure.

Can someone give me advice on using GPS mapping software for locating these dwelling houses and properties.
