Hi MurphyK91
I take it that your Great Grandmother was the daughter named Catherine (Kate)?
1871: Port Dalhousie , OntarioPatrick DYER 28, b Ireland, labourer (abt 1843)
Mary 25, b Scotland (abt 1846)
Catherine 7, b Scotland (abt 1864)
Rosanne 5, b Ontario (abt 1866)
Mary Jane 4, b Ontario (abt 1867)
Bridget 3, b Ontario (abt 1868)
Margaret 2, b Ontario (abt 1869)
Elizabeth 2mth, b Obtario (1871)
ROMAN CATHOLIC.
Above them: - Is this Patrick's father? sister?
Michael DYER 68, b Ireland, Labourer
Catherine 35, b Ireland
Mary 13, b Scotland
Sarah 10, b Scotland
1881: Toronto, Ontario enumerated in this order:
Maggie 16, (b abt 1865)
Mary 44, (b abt 1837)
Kate 18, b (b abt 1863)
Rosa 11, (b abt 1870
Jeanie 14, (b abt 1867)
Elizabeth 10, (b abt 1871)
Sarah 8, (b abt 1873)
Bridget 13, (b abt 1868)
I see what you mean about Rose and Margaret, possibly having ages transposed in 1881
There is a FINDA Grave, which says Patrick died 1876 (but no sources)?
https://www.findagrave.com/cgi-bin/fg.cgi?page=gr&GRid=168594006I think this is your 'Finda Grave page' though.......linked to Kate's?
Do you know when Mary his wife was last known to be living? I see her age is a bit out of sorts between 1871 and 1881, too.
Cheers
