I am a descendant of Otto Yeske through Carl's brother Edward. His son William Harrison Yeske was my great grandfather & his daughter Marjorie Yeske McMullin my grandmother. Not sure by reading these other post if this is the same Otto & Carl Yeske that you are looking for. From the information I have the name was spelled at one time with a "J" Jeske as the "J" has a "Y" sound in Germany. I don't have hardly any info on Otto & a little on Carl but would be happy to share. Please contact me at my email address
lissie24@msn.com with Yeske in the subject line. Hope I am able to help. Melissa Guyett
