W M Smith	28	M		Clerk Foundry	1000	300	New York

Nellie Smith	2	M					Wis
Mark Hopkins	29	M		Pattern Maker		300	Mich
Ann Hopkins	24	F					Canada
Walter Hopkins	3	M					Mich

Mark's brother married a SMITH, so I suspect there is some relationship here.  It looks like the SMITHs moved from WI to MI about the same time as the HOPKINS.
