Carol Elfbrandt (Mills) - Carol Clarke -

Clarke was her maiden name - Descendent of the Orange county NY William and Sarah Bull (bullstonehouse.org).
Mills was from prior husband. I haven't found proof yet, but Captain Mills may have been her second marriage. Her trunk is in my dads basement. It has a diary I have yet to read.
Army Nurse at end of WWI. Kept her RN certification for a long time.
