I saw your post and I thought I could help; I went to Ancestry Family Tree pages and found that Martha Stillwell was born 4 Feb 1777 in Greencastle,Franklin Co, Pa. and died 7 June 1857 in Prairie Ronde, Kalamazoo, MI. Find a grave memorial #is 17416361. I also found in Ancestry Family Tree pages that her father is named Elias Stillwell, born about 1745-50. I did not see a mother listed but I am sure she has one. I will try to help if I can. She had quite a # of children listed, do you have those? I am not sure if they are all hers since some of them were born in Butler Co. Ohio.Let me know if I can be of any help to you. Nancy
