You can always put in a request to the FOD site - to check the Register - I have done this a couple of times and have had a very good quick response.

Under the heading 'Possible Transcription Errors'

with HULIN/HULING - an explanation might be there.....

I've been to the Records Office a few times - and these documents are very old, and sometimes on Parchment etc. and the Transcribers must have a very difficult job.
