I am looking for William John Olson, son of Olaf and Caroline Monson from 7 Flint Place, Boston, Ma. Any or all of his siblings were: Albert, Andrew, Matilda, Peter and Victor. William John Olson married Hannah Sophia Anderson, daughter of Peder and Mare Anderson from 215 M. St. Boston, Ma. Any census of my grandparents (William and Hannah) at these addresses would be greatly appreciated. Thank you in advance, George Olson
