Gary,
I would love any information you can share on the Jaycox family. I am a descendant of Isaiah Jaycox thru William and Mary "Polly" Ann Carter Jaycox. I have information from the national archives I would be happy to share. When William was called to serve during the Civil War (from Kansas) he had to enlist under the name JaQuash and provide documentation that the family name had earlier been changed to Jaycox. After that he and his children used the JaQuash name. It's also spelled Jayquash at times.... interesting. Look forward to hearing from you
