I don't exactly understand why you clasiffy the VARIANTS or ENGLISH FORMS of original Biblical names as "Biblical", but the original names themselves you leave as unclasiffied. (as you did for CHAANAH, YEHOCHANAN, MATTITYAHOO, YUVAL and more.)
Anyway, most of this names in the original Hebrew form are used as Jewish names.
as for CHESED - I know you only asked for definite answers, but I'll tell you what I think anyway: I think it can only be Jewish, but very rare as a first name. (and I only say "rare" and not "unexisting" because for almost every Hebrew word with a positive meaning you can find SOMEONE who wears it as a name.) In other words, unless you know otherwise or got it from another source, I THINK you can safely delete it.
