Yes, this is my husband's family! His mother was Irene Grace Meyer Hartman. The book should be very helpful.
However, her sister Albertine, who lived near Big Rock most of her life was born at Wolfs Store, PA. She was married in 1930 in Big Rock, IL and passed away 27 Dec 2005.
Her sister Gladys married Ivan Williams. We hope to see her at the Meyer family reunion tomorrow.
Thank you so much for responding. I will try to contact the Ross Library that you have suggested.
