were your great grandparents educated? (formally)

[J. J.]

I am not sure if maternal grandfather could read either English or French.

My paternal grandfather graduated from high school, I think as did my maternal grandmother.

My paternal grandmother had a "teaching certificate," which indicated at the time that she had completed HS and was certified as being a "good enough" student to teach in the public schools in the early 1900's.

None had a college degree.
