I'm quite sure that 'Taze' comes from the name 'Tace'. This is a 16th century name used by the puritans / presbyterians. It is a so called 'Virtue Name', used to remind it's bearer of the godly vitues s/he should aim at. More examples still it use today are Faith, Hope, Glory, Prudence, Joy, Charity, Honour, Amity, Felicity or Justice. But there were also some rather unusual names like Do-good, God-help, Hate-evil, Sin-deny, Have-mercy or even 'If-Christ-had-not-died-for-thee-though-hadst-been-damned Barbone'(unfortunately the person named like, "whose morals were not of the best" according to the sources, was known to most people as Damned Barebone!!!) LOL
...oh, I almost forgot: Tace is derived from the latin 'tacere', to be silent...
