means People connected to you by blood or by a deep, shared affinity — your family, your tribe, the ones you feel related to.

from From Old English 'cynn' (kin, family, race) — the same root behind 'kin' and 'kind' — joined with the suffix '-red,' from Old English 'rǣden' meaning condition or state (as in 'hatred'). So 'kindred' is literally the *state of being kin*. The intrusive 'd' crept in during Middle English, where 'kinred' picked up an extra consonant the way 'thunor' became 'thunder' — the tongue likes to slip a 'd' between an 'n' and an 'r.'
