Most Revolutionary War companies were recruited locally. Although a regiment may have contained companies from multiple towns or counties, a company was generally organized from residents of one locale. This makes knowing your ancestor’s residence key…
Why? If your ancestor didn’t reside in the county or town from which the company was recruited, it’s unlikely the military service actually belongs to them. Same name mix ups are common with Revolutionary War service, as company records may provide no details beyond their name. The residence and name should both match your ancestor.
To determine where a company was recruited, check the residence of the officers. Since they had to organize and train the unit, they typically wanted to stick close to home while doing so. They lived where they recruited or with in a few towns.
