I'm back from a bit of a self-imposed sabbatical, and I have some new resources to share with you! I'll put them out one at a time just so that something that might be important to you doesn't gets buried!
Ontario Mennonite, Amish and Brethren in Christ family history now has a home online at the Ezra Eby Revived! site. As the site explains,
In 1895-1896, Ezra E. Eby [1850-1901] published a 2 volume works entitled "A Biographical History of Waterloo Township". This website not only shows the pioneers found in the original "Eby books", but also many of their numerous descendants.
The site welcomes additions and corrections and offers a basic search based on name, in addition to access to the text if you don't own a copy of the text itself.
