William Jeffrey and Mary Lyall
 Family History and Bi-Centennial

  Cobourg's Grand Vision: Victoria Hall


This is the family genealogy and stories of William Jeffrey and Mary (Lyall) Jeffrey who arrived in Upper Canada in 1820, settling in the Cobourg area.

Here we assemble the researched information on our Scottish immigrant family, their ancestors and descendants. We strive to have well-documented facts and show where facts are weak.

Search here to find information we have documented for ancestors or (deceased) descendants of William and Mary. For each person you will see Notes and references to the Sources we have used. Actual source documents are in John Cowan's Library that he is willing to share with interested family members. You can also view charts or trees showing relationships.

Several of us are planning a CELEBRATION OF THE BI-CENTENNIAL(+2) of William and Mary's arrival in Cobourg. This family gathering will take place in Cobourg, Ontario Sept 16-18 2022. Cobourg and Ontario are great places to visit, and you will meet new and familiar cousins, from near and far. We are planning special events in Cobourg outlined in Feature 3, above. We welcome you to contact John Cowan (see below) for the latest details.
