The citing of parents in Death Vitals in Ontario, Canada did not take place until the 1900s (Marriages were hit and miss). The Ontario Vital Stats did not begin until 1869. As I mentioned, I am in possession of Hugh and Catherine's Family Bible. I will include the census records, and a couple of documents that show her maiden name was Brown.

The Hugh and Catharine Wight Bible is embossed HUGH & CATHNE WIGHT - the NE on CATH is smaller
The Bible has the death dates for Hugh and Catharine. I could not post any actual documents due to size issues. Sorry.
