X00060 Sybil Williams Death Information

So, here's the issue. I'm trying to find a death record or death information for a Sybil Williams (born Sybil Foxwell) (Feb 17 1798 - May 13, 1874)



Here is the known information:

• She was born February 17 1798 in Gloucester, England based on her baptism records [Sources: D00157, D00419]
• She died May 13 1874 based on her tombstone and the Greenwood Cemetery Internment listing [Sources: D01131, D01637]
• She was buried May 15 1874 Greenwood Cemetery, Owen Sound, Ontario based on the Greenwood Cemetery Internment listing [Source: D01131]
• Her religion was Church of England [Source: D01565]
• She was living in Owen Sound in 1871 based on the 1871 census [Source: D01565] and Guelph before that.

Here's the results of my research:

• Couldn't find anything in the Ontario Civil Death Registrations on either Ancestry or FamilySearch
• Couldn't find anything in the Ontario Civil Death Registrations on microfilm
• Couldn't find anything in the indexes of Owen Sound newspapers
• Couldn't find anything in the indexes of Guelph newspapers
• I found a death certification for a Sybil Williams in England in 1874, but it is not her [D03877]

Any other suggestions of places to look? Or next steps to try?
