there are bapts post 1911 but it looks as tho the index is very incomplete with only a few parishes showing up - I think there are also gaps in 19th C records as not all parishes are completely entered - don't forget the use of * as a match any string thus c* would bring up many names starting with C but fairly painless to just look at the costain etc (obvious best used with the year range )

However you are getting into living person range and not everyone appreciates long distant relatives publishing family details (wch is actually illegal in some countries under privacy laws)
