Apparently if using GRONI online:
You have registered to use our Online Search facility, that is not an application for a search.
Should you require further assistance if your search is unfruitful you can apply for a search by telephone ... or by downloading an application form from our website (something I have yet to find - anyone found it and have a link?) and applying by post.
so, if a record you believe should be there (perhaps because you already have a Volume and Page number or other proof), does not turn up on the online search, and according to GRONI, when asked, has not been mis-transcribed, they will, it would seem, not assist further by checking for it manually in the appropriate Volume and Page (if you have this information) of the appropriate original register, which they hold. However, if you apply for a search by telephone or by post, and pay separately for same, they seem to
imply they would perhaps check manually (albeit it is not clear if that is indeed what they are saying).
Unrelated to the foregoing -
Useful TipCame across this on one of the many 'info' pages on the nidirect 'parent site':
http://www.rootschat.com/links/0ytc/ Illegible names
There are several reasons why names may not have been recorded for example if the name is illegible and has been impossible to capture for the index. In these cases ‘not captured’ has been inserted to enable searching.
For example, if you are searching for a George McDonald that you know was born in 1868 but cannot find the record, it may be worth replacing the forename with ‘not captured’. It is also common in the case of older records that a birth was registered before the forename of the child was agreed. In these cases ‘not captured’, combined with the surname, may help you find the record.
It might help someone, hence why I thought I would post the details. That said, I have already come across entries that have actually said 'Illegible' in the surname space on the 'enhanced results'.
