(This January 2013 update regrding the coordinated search for parentage of Wiliam Douglas gives the following information (small part of data)--dropbox organized for discussion of this information):
Betsey[Howes] found the ships that came across the Atlantic in 1640. Julie [Hornung] has just discovered a passenger list
that contains references to William and Anne and two children landing in Boston in 1640. There are
reference numbers with the entries and Julie is working to understand reference numbers.
