I wonder if this entry found on FamilySearch is relevant to them:

BUT IT IS AFTER HIS DEATH!!!!  OOOPPPSSS!

Name: Gulielmus Broadhead
Spouse's Name: Maria Woodhead
Event Date: 1669
Event Place: Almondbury, York, England
Indexing Project (Batch) Number: M01712-1 ,
System Origin: England-VR ,
GS Film number: 230649 ,
Reference ID: 2:1DMLLMB

Guliemmus is of course Latin for William, and Maria is for Mary.  The marriage date of 1668 is 17 years before the marriage of Elizabeth, their possible daughter, which is just believable for those times.
