I am working on a problem that has to do with Revolutionary War service. I find the subject in the published PA Archives receiving “Depreciation Pay as per canceled certificates on file in the Division of Public Records, Pennsylvania State Library.” Actually I find two people listed who could be him, one a lieut. and one a private. Do you know if this list was taken over time and perhaps the private became the lieut. or was taken at the same time and they are two people? Or …?
My sense is that they would be two different people. If you look at the introduction to Bockstruck's Revolutionary War Bounty Land Grants Awarded by State Governments (which does not index these depreciation grants as he does not consider them to be truly bounty land grants) it says that these lands were intended for compensation for the depreciation in Continental currency (Not Worth a Continental), script in the form of certificates of depreciation were accepted as payments for lands in the Depreciation Tract. I don't believe that it had anything to do with rank.
Hope this helps.
