If you look on Brian Lawson's site, you will find Dissenter baptisms:

Also on Brian Lawson's site - Dissenter marriages

21 Nov 1844 Joseph Boyd & Catherine Mills, ( The R.C. Register shows James Murphy & Lucy Carville as witnesses.)

St Mary's R.C. School records show Jane Carvel who was admitted in 1864 and on 1865 Examination records show she would be 10 on her next birthday. She is also on the records for 1866 & 1867 aged 11 & 12 yrs

There is also a John Carvel in 1867 records who would be 14 on his next birthday.

If I come across anything else I will let you know, hope this helps. Marie Radcliffe
