I was only able to view this census record only at 100% on Ancestry. Don't know how you all were able to read it!
I was able to download a higher quality census record at the Archives of Canada site which took forever to download, maybe a slow night on the internet...
I will email the info to you if you wish.
I think the niece was born in Saskatchewan.
As for the name, parts of it looks like "??abel" so I would be guessing it as Isabel.
Nice work with the transcriptions.
