father's father VS mother's father?
I need to mention both my father's father and my mother's father in one essay, how could I make it clear who is who? Both of them are grandfather in English :(

Question

Answer

You can say my grandmother on my mothers side or fathers side. For example: my grandmother on my fathers side is from Scotland, while my grandma on my mothers side is from Peru.

You can also say my father's mother is from Scotland and my mother's mother is from Peru.
