For four generations, descendants of brothers Lucius and Henry Robinson have roamed the halls at Hartford’s Robinson & Cole. But alas, the fabled 154-year span of Robinson lawyers, which began when Lucius hung out his shingle across from the Old State House in 1845, will end with the tentative retirement of Barclay Robinson Jr., Henry’s great grandson, on Jan. 1.

Though Barclay Robinson is a key figure in the 165-attorney firm’s governance, serving on its hiring committee and, until recently, heading up its labor practice, the Robinson family has long since relinquished the firm’s reins.
