Looking for Garnett of Michigan Canada

I have been doing research on the Garnett family for many years.
George Garnett was born in England in 1833, He married Rosannah Ellen Davis in Elgin, Ontario, Canada in 1858. Around 1865 they came to Michigan, lived in Richfield, MI. Genesee co.

George was listed in the 1880 census and not the 1890 census. I have not been able to locate a death notice or burial place for him.
As for his wife Rosannah (Rose, Rosana) I have found a death notice for her saying she was born 1840 in Canada, and died in Romeo, Michigan, supposedly burried in Lakeville Cemetery, there is no grave or record of her being burried there.

Anyone who has any information is welcome to write to me, I have informaton on other members of the Garnett family and would be glad to share this with others.
