I was also looking for information on the Rishea family and came upon your post. My father and mother were very good friends of Amie and Edith Rishea of Peterborough Ontario. Their granddaughter was Veronica. I recently reconnected with her brother here in town. Edward but known as TED. He did tell me that Veronica had passed on.
I have looked up the website that you suggested.
If my memory is correct. Amiee's father and his brothers came to Peterborough as Lumberjacks and Labourers while the Peterborough Lift Locks were being built. When the work was completed some stayed and some moved up north.
Amiee worked at Canadian General Electric and then became a butcher at Canada Packers and worked there until he died in 1957.
