Thank you for your reply and for the information... I remembered your name, and what a surprise I found when I read your message!
I believe this to be the same family of Yerkes. Our Mary Ann Yerkes married Elijah B. Clark (who came to Oakland County with Asa Owen in 1831). I believe Mary Ann's father was Joseph Yerkes. I need to review my files to be sure.
Mary Ann (Yerkes) and Elijah Clark were the parents of our Charles Owen's wife, Elizabeth Clark. Charles & Elizabeth (Clark) Owen had ten children and one of their daughters married a Purdy (one of the names you have listed with the Yerkes in the index).
This is probably more than you wish to know this early in the morning, but I would very much like more information!
You may contact me off-line if you wish. I hope we may be able to arrange somehow for me to buy your copies of the mentioned pages from your book(s).
Thank you again, and I hope to hear from you again soon!!
