I've never been able to actually read the court records so I couldn't tell you about that. I have one illegimate great-great grandfather and was once advised to check the local court records for possibly more information about the father (I believe listed with wrong name in the parish books.)
But - I can't read those court records for the area I'm interested in. The parish records are EASY by comparison.
Maybe one day I'll have enough experience with the bad handwriting often found to try it again. I have plenty of other family tree branches I can work on...
Punishable doen't mean punished -- just sayin'
