We are trying to find out information regarding the sister of my husband's grandmother, Emillienne Jeanne Mahieu who was born in Dunkerque on 11th November 1900. We believe her sister's name was possibly either Suzanne or Elianne Mahieu but we have no idea when she was born or if she married. We do know that in 1950 she was living at 17, RUE PAUL BERT, MALO-LES-BAINS, DUNKERQUE with daughters, Odette and Leone.
Can anyone please tell me how to find out the names of those living at that address for that period? Is it possible to access the electoral role or are there any directories which might list this information?
