Hi,
I found William jr Viola and his family Census 1901. See
http://www.automatedgenealogy.com/census/ProofFrame.jsp?id=2...William jr born in 1855 and Ann his wife born in 1870. If William jr is the son of William and Ann, they got married in 1855 or before.
It looks like there is 2 William and Ann or with similar names.
https://familysearch.org/pal:/MM9.3.1/TH-1942-28004-7471-22?... This couple can't be the one on the census. I don't find any baptism of the children from the census. They are from Church of England.
Have you seen this act ?
http://interactive.ancestry.ca/1091/d13p_00290623?backurl=ht...Georges Arthur, born in 1850 ? and baptised in 1882 ? In the margin, we see 1850, in the act, the priest wrote mil huit cent quatre vingt cinquante, which is impossible. Translation is one thousand eight hundred eighty fifty.
If it's the good family, William Viola Vignola ... and Ann Mosley were married before 1850.
