Hi Cheryl,
My grandparents are Alexander Learmond and Isabella Hilda Pearce (and I suspect the previous poster, Jean, is my cousin actually). As Jean said, they had 11 children, my father being number 7, James (Jim).
What I am not sure about though is the Margaret you mention though the eldest child was Hilda Margaret but I understand she married an Armitage and a Schroder (but I can check those details).
My great grandmother, Isabella's mother, was actually Margaret Pearce (nee Johnston) which is the relationship to the lemonade company.
Best wishes
Stephen
