Elsie Margaret Grant (Lawson) - Missing one child?

Hi, my names Karly gannaway and my grandmother is part of this family tree, her name was Elsie violet grant born 25/6/1931
She passed away in 2016,
I am keen for more information on this side of my family because my grandma didn’t know many of her siblings or her family history and I’d like to know it
Thank you
