<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">kith and kin</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this before)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for family circle that I've seen before include "Kith and kin" , "all my relations" , "Collectively" , "Close kin - cheap theatre seats (US)" , "Group composed of one's relatives" .)
