your good name

In modern South Asian English, likely calque of Bengali ভাল নাম (bhalô nam), Hindi शुभ नाम (śubh nām, literally “good name”), and similar collocations in other Indian languages.

The archaic sense is a mark of respect in quaint English, such as "Tell me, my good sir, ..." or "...your good wife..."

Another way of saying, "...your honourable ...".
