Interested in contacting a descendant of Sarah Paine Koffman shown as a resident of Iowa City, Iowa on the records of the US National Archives in 1939. The Koffman surname may be subject to alternate spellings in this case, but I have a copy of the original handwriting from the Natl Archives and it is definitely written as "Koffman". She was researching the War of 1812 record of Willis Lake of Licking Co, Ohio. I wish to exchange information if convenient to both parties. Thank you.
