Hello ? You requested a reply regarding the 1870 Census. Can I make a suggestion to at least give a first name as people are more apt to reply to a name. I have checked my Census Records and I do not come up with Royal Lawrence for 1870. It is possible he was process of moving and missed the Census in both his prior home and where he was moving to. Could I suggest that you consider checking the 1865 State Census, Directories and see if they will show anything for him. The LDS (Mormon) Church Family History Center nearest you would be able to order it for a small Fee of $5.50 and you could then view it on their reader. If you live in the area you could call the St Lawrence County Historical Society and see if they have the State Census available. Good Luck Pat R
