Hello Michael,
Unfortunately Matthew did marry Christina Martins. Verified by Cornwall OPC, as well as 1861 England & Wales Census where Christiana and Matthew appear. The Elizabeth Jane Chapple on the same Registration married Robert Osborn. Her father is James Chappel.
As you can see a very elusive lady.
Thankyou as well to Maureen for supplying link to Family Search.
Regards,
Christine
