Peter Knisley is my gr. gr. uncle born in Markham to John Anthony Knisley and Elizabeth Pheiffer. I have Peter Knisley with his family up in Simcoe co. in the 1891 census. I can scan it and send it to you. I don't know really when he died but I have a Peter Knisley that died in 1897 in York co. and he could be living with a child after his wife dies in 1896 or 95 have to check my records. I do have alot of this family just because of the Yake connection.
