I think that Mary Ann Digby was born in the 2nd quarter-Apr-June, 1849 the Spalding, Lincolnshire. This would make her 16 when she married Solomon in July 1865. I too wondered about the age difference. Pretty amazing that Solomon fathered 5 children after the age of 55. My next step was to look for a divorce when noting that Solomon was still alive when Mary married Fred Spuhler. Did you find the divorce record?
Were either your Aunt Lois or Uncle Jasper buried in Victoria? I go to visit my mother in Victoria several times a year. If they are in a Victoria cemetery and you would like pictures, let me know.
