If the person in question was a paid cook/nurse or other civilian, she would have records through the paymaster. Cooks and nurses were paid 10.oo per month and one ration. This was the same pay that black soldiers received before their rate of pay was rectified two years after the fact.

They may also have records with the quartermaster, if they purchased stores. If she was part of a family living in a government contraband camp there may be records of allotments. I don't know of any civilians who received pensions. Good luck
