Hi everyone that has helped me with Isabella Hartley's birth. I've had a breakthrough! I odrered the birth record for Samuel and Isabella's daughter Isabella from DROL. I realised she had been born after the death of Samuel in 1799 so wondered what her birth would reveal. All the other children's births just said son/daughter of Samuel Dickinson weaver by his wife Isabella but Isabella's said....Isabella Dickinson of Chester le Street born 3.8.1799 daughter of Samuel Dickinson weaver, native of Heworth, Deceased, by his wife Isabella Hartly native of Gateshead. Other records I ordered say Samuel's deceased children died of Smallpox so it could well be that Samuel died of smallpox also.
Thank's again C-side and Radcliffe for your help.
Heather.
