Well, actually, one's almost solved, because there's another angel with the same name, but I was wanting to just check...
From this page (A-Z of angels):
HANIEL-Also Hanael and Aniel [...]
I'm assuming Anael is also an acceptable variation?
The other one needs a bit more help. I want his name to mean "pure one of God". Searched Behind the Name and got
Zacchaeus
From the Greek form of the Hebrew name זַכָּי (Zakkay) which meant "pure".
Can I just stick the -el suffix onto Zakkay (Zakkayel? Zakkael?) or is there some other translation I've missed entirely?
Thanks in advance for your help! ^_^
