Sadly I do not know much about John Ezard's family. I have a fair size collection of records and newspaper clipping but that is about it. I assume the Sarah you are talking about married Howard Baker?
In 1861 John and Hannah, my gr grandfather, their sister Ann, Isabella, Jane and George the youngest as well as their Mother were all living in York County. My Grandfather in York Twp. the rest in Vaughan Twp. Shortly after the 1861 cenus. the daughters and their families moved north taking their Mother with them. In 1871 John and Hannah are found in King Twp., York County, my Grandparents in York Twp., York County. Mother and Ann are dead. Isabella, Jane are living in Brant Twp. and George the youngest is found in Toronto Twp., Peel County. Bruce County, hmmm Jane was living on the Grey Bruce townline. By 1881 John and Hannah had followed their daughter Mary Jane east and settled in Osnabruck and the family in York and Bruce Counties never heard from him again.
I am quite willing to share anything that I have, let me know what you are interested in. Merle
