Where is Gereaux Island Lighthouse?

Gereaux Island Lighthouse was built in the late 1800s. It is on the northern tip of Gereaux Island marking the entrance to Byng Inlet from Georgian Bay, Ontario. My aunt shared the picture of the original lighthouse.

Two of the people from my family tree I hope to focus on are Joseph Normandin (Jr.) and Louis Normandin. Around the time that Joseph Normandin (Jr.) moved to the Byng Inlet area the family name was changed to Lamondin (more on this in a later post).
