Among the many books prepared by Lilian are three that document the Dumville (Clark, Parker) connections. You will find many photos, stories, and documents related to these family lines. I particularly appreciate the many old photos and original documents included in these collections.
These three book are in pdf form and password protected. If you would like to look at them, contact Bill Reimer for the password. You can download the files by clicking on the links below. If I am unlikely to know who you are, please let me know a bit about you and why you are interested in the contents.
I hope you enjoy these as much as I have.
