I have also found the obituary for Annie Amelia Ball for her death on 14 Apr 1947. It was shown on the front page of the 14 Apr 1947 edition of the Columbian:
I am still a bit puzzled by the reference to two sisters living in England. As far as I am aware, there was only one sister (Alice (Turner) Boyle) left in Cardiff, Wales.
Her other sisters, Eva Byatt (deceased), Sarah Elizabeth Hewlett(deceased) and Edith Steed (Mrs. R.E. Steed) had all come to Canada with or shortly after Annie arrived here with grandad. Should I chalk it up to my grandfather's lack of accuracy? Or is there some truth to the matter?
