Looking at a 1957 rancher. Was aluminum wiring common in the 50's.? I
will check it out further myself.

And...Most of the outlets are 2 prong. If I put a GFI at the head of
the curcuit will that protect the downstream outlets so I can replace
with 3 prong?

Aluminum wiring was used in that time frame.

You can use GFIs and protect circuits downstream, but they will not be
grounded. Grounded requires a ground conductor.
