Hello Kim,
I know that you posted this years ago, but I would be interested to see your copies of John Eyer's family bible, if you are willing to share. John Eyer was my 5x great grandfather and I've been trying to make the link to his father (Abraham Eyer) through documentation and haven't had a lot of luck. You can contact me at stacey.l.w.lee [at] gmail [dot] com.
Thanks!
Stacey
