My grandparents' farmhouse was located at 4206 West Capitol Drive, and when my parents moved into it in 1946, there were only three city lots left. We lived there until the fall of 1956, when we loved to 156th (Lilly Road) and Burleigh Place in Brookfield--on top of the subcontinental divide.
One empty lot at the NW corner of 42nd and Capitol was made into a dime store around 1950. It was then owned by Aaron Cohen, whose son Wilbur J. wrote the Social Security regulations for a professor (Thompson?) at UM or MSU, who in turn worked for FDR. Wilbur later became the Secretary of Health, Education, and Welfare cabinet position under LBJ.
In 1968, the house there burned down while it was being disassembled for its materials after the stupid workmen forgot to disconnect its electrical power! But it was being torn down anyways... Its double lot was converted into an office building rented by the state for a welfare department branch. Today, ex-Packer Willie Davis (Super Bowls #1 and #2) owns the property.
An exact replica of that farmhouse still exists about two blocks north on 42nd Street. I believe my grandfather's brother lived there at one time. Ditto for another, newer house in the middle of the block on Capitol between 41st and 42nd.
