FreeBMD has only transcribed this once so far, probably from the rather fuzzy tif file, and gives it as KERRNISH.
There is also a jpeg of the same image which is clearer, and is definitely KERRUISH.
GRO index gives the second forename as CHRISTIAN, but the mother's maiden name as CHRISTEAN.
Was the GRO transcriber having an off-moment, and put the correct MMN in the 2nd forename box, then mis-spelled it in the correct box?
Suggest reporting a double error to the GRO, from the foot of the search page. Your reason for reporting will be the jpeg file, ref ANC-05/1895B1-M-0395.jpg
If they accept that, then you can report a different error to FreeBMD!
