I understand that your issue is with the previous generation, but in order to sort the confusion out, it would be helpful to identify these families on the census, working backwards from something solid. So Frank and Blanche are something solid. Frank on the 1911 census is fairly solid. Joseph Louis and Albina/Ermina/Hermina got married in May 1900, so now we can look for them on the 1901 census. They might still be living near their parents. Looks like her mother's name Melina might be Emilina sometimes....
