This confirms the above.
Nora Agnes Turnbull's birth registration is on the SP site posted, she appears as Nora age 4 on the 1921 census, there is also Agnes age 30, I presume her mother.
Also Agnes 65, her grandmother?
It looks like the only other is George 28 but you would need to see the census on SP.
On the 1911 census in Lilliesleaf Agnes 20 is present together with a James 65 but not Agnes senior but that will need to be checked. Below looks like Nora’s mother born 1890 and her parent’s marriage. I hope this gives you a start in your search.
