Thank for responding. Its quite a mystery.
My great grandfather William sr. apparently died in York in 2012, His wife Emma (Mary) Morley died in 1881.
There kids: (William jr, Annie, Alex) lived in York I believe. The 2010 directory shows William jr. living on St. Clair Street. His wife Annie Foy Cooper gave birth to Robert Cooper. I believe the others may have lived on Duggan Avenue. Very sketchy.
I wondered why Wlm jr and Annie Foy Cooper would be there for only a short time when they have a family in Montreal.
I thought it might be was for two reasons. They were visiting Wlm sr who may have been very sick or there were Foys living in the York neighborhood.
