"As they are copies of the par regs, the fathers would be named on illeg birth records if they were named in the register"
not exactly true - the lists to convocation were transcribed from the registers but sometimes the vicar added info that was not known at the time of entering into the register - there are later BT's (+ some that fill in the gaps) still unfilmed - those that have my cd will find my transcriptions - likewise for marriages + burials
