I will ask my mom to confirm about the "e" in the yeingst name.
The story I remember is that your grandfather's name was misspelled on the birth certificate and this was not corrected. Many births were at home and the information was left "as is" once it was written down.
Your grandfather is my mom's brother. She is a twin and will be 82 this September.
All of her siblings except for your grandfather had the Yeingst spelling. Your grandfather, my "Uncle Dewey" was the only one of ten children to have the Yingst spelling.
Once I complete a rough "tree" of the Yeingst/Yingst family I would be glad to share it with you. You have a large estended family in the states. If you ever come stateside, it would be great to meet you.
Feel free to email directly
at...swhuntz@hotmail.comI would love to hear about your families in Hawaii. I really have lost touch and only know bits and pieces of where everyone is.
