Unfortunately I never knew my grandparents. My father led a difficult life and he died nearly 25 years ago. I knew his brothers and sisters as a child but not that well and they are all dead. The only other name I can find is that she was registered at the same house in Swansea with a Daniel Doyle the year before she got married...1919. I cant see that he was born in Swansea and havent found him linked to john doyle or Anastasia doyle. No idea what relation he is to her. I have found an Anastasia Doyle with a John Doyle engine driver as a father on the link you sent born in May 1893 rather than November 1893.
