I've not been able to find anything for a Rose Jennie (Jane or Jennifer) Ducker as yet. If her first two children were born in the workhouse would it be worth me ordering their birth certificates? I can see on their baptism records she was noted as 'single woman'. Would there perhaps be additional information on the birth certs?
I have been trying to find some evidence of why she would have come from London to Norfolk, either on her own or with her family. I have found a record of a William H Jones (born 1863) and wife Hannah Jones (born 1861), with a child Rose Jones (born 1883) and sibilings Leonard and Edith in the 1891 England Census. They were residing in Great Ellingham, Norfolk, England. William is noted as being born in London. However, Rose is noted as being born in Great Ellingham. Could this be a lead or another red herring?
