We know of the existence of three sawmills at the beginning of Cumberland Township’s history. We will review their existence, purpose and location and then jump to the 1861 census to identify the large scale logging that was going on then.  Presenters: Gérard Boyer and Thomas McNeely.  7:00 p.m., Lori Nash room, Cumberland Branch of the the Ottawa Public Library. Please note the change in the original date from Mar 1
