Hi Mike and Marian,
Thanks for the tips,have had a good look at Marriages but all ends up on a roundabout,going no-where.The Death registration sounds interesting as I don't think there were many Marias' about and it may be worth getting a Certificate on that.
According to my records Maria(daughter)would have been born c1843,Maria senior would have been in her mid-30s.Have checked GRO Images and there is an entry on March 1843 record for a Maria Bennett,B.Manchester V20 Pg633.Have checked all 1843 quarters and 1st quarter 1844,no other Maria born Manchester(or Salford)so will have to spend up big and go for Birth Cert for Maria jnr and D.cert fo Maria Snr.Will let you know results.However,while this could solve 1 half of our William-Maria puzzle,William is still out in the unknown.
Best Wishes,
Rob
