I am hoping someone may be able to help me. I found the following McLeods on the 1920 census in Alcona Michigan,

Name: Murdock Mcleod
Residence: , Alcona, Michigan
Estimated Birth Year: 1846
Age: 74
Birthplace: Scotland
Relationship to Head of Household: Self
Gender: Male
Race: White
Marital Status: Married
Father's Birthplace:
Mother's Birthplace:
Film Number: 1820753
Digital Folder Number: 4311578
Image Number: 00089
Sheet Number: 5
Household Gender Age
Murdock Mcleod M 74y
Spouse Jane Mcleod F 68y

I believe that Murdock's wife Jane is the sister of my great grandfather John Smith. Can anyone tell me what other information appears on the census? I have access to Ancestry.ca but it does not include U.S. censuses.
Also since I cannot find them on the 1930 census, I am assuming they both died between 1920 and 1930. Is it possible to find a death record or place of burial? Both of them were born in Scotland, lived and were married in Ontario, Canada and moved to Michigan in the early 1900s.
Any help would be most welcome.
