copuliert

The word comes from Latin copulare, to join, and in old church books it simply means wed. Marriage registers were often headed Copulationen or Kopulierte, the couples married that year. Duden marks this sense of kopulieren as outdated legal language for trauen, to marry.

Modern German uses kopulieren mostly in a biological sense, which can surprise a reader using a modern dictionary. In a church book there is no doubt: it is a wedding.
