I found a Raymond Michael in the 1880 US Census living in Claverack, Columbia, Co., NY, age 29, occupation, Painter with, presumably, his mother Elizabeth Michael, age 60.
Possibly these are grandparents/relatives of your Raymanond Michael of Rensselaer, NY.
It's really easy to use the 1880 US Census at the IGI web site. You just enter the person's name;in the category "event", enter "other", then the date 1880, then the state. Household census data are quite revealing.
