Dundas County originally consisted of 4 Townships.
1. Mountain Twp (north west)
2. Matilda Twp (South west)
3. Winchester Twp (North east)
4. Williamsburg Twp (South east)
In recent years they amalgamated the townships into basically North Dundas and South Dundas.
Just to name a few, Mountain Twp would have included the villages of Inkerman, South Mountain, and Hallville.
A lot of the old records have been transcribed. I do know of someone who might be able to help. Contact me if you'd like their e-mail address.
