From the Library of Virginia and its online catalog:
Public Record Office Class E. 190/41/5. Port Book. Port of London. Waiters. Overseas imports. Ackland, John -- master of ship -- lawsuit involving -- 1638, SR 03499, p. 16
Don't really have any additional information to put this information into context; merely an Ackland (I use Acklin or Acklen) surname find in the Library of Virginia.
