Collins

I'm looking for information on former Muskoka (and before that Garafraxa) residents from the Scottish/Irish migration around 1855-1861. Family name is Collins.

Edward Collins ( born 5 AUG 1813 but there are different records so far reporting birth years between 1813-1819 • Northern Ireland - died 11 NOV 1897 • Hastings, Ontario, Canada) and his wife Mary Conway (b. 1821 • Antrim, Northern Ireland), and daughter Margaret Collins (b. 14 OCT 1851 • Edinburgh, Midlothian, Scotland) lived in Edinburgh, Scotland and immigrated to Canada in the year 1855 or 1856 (as reported/recollected by Margaret or a housemate in later life US census records). It's unclear if this arrival time is exact, as Margaret would have been 4 or 5 years old at the time and may misremember.

The first known record that supports any arrival in Canada is the 1861 Ontario census in Enumeration District 2 in the township of Garafraxa in the County of Wellington. Listed in the Garafraxa household is Margaret Collins 10 years old, Edward Collins, Mary Collins, (there are also 7 other children listed under 18 years old).

The next known Canadian record for Edward Collins is the 1871 Census of Canada, this lists him in Morrison, Muskoka, Ontario. His birthdate is reported different than what I initially had, it says 1808 not 1813. His wife Mary is listed as well.

The next known Canadian record for Edward Collins is the 1881 Census again listing him in Morrison, Muskoka, Ontario, Canada, though now it says his birth year is 1817.

We're having so much trouble finding records of this family in Garafraxa or Muskoka if anyone has any leads.
