I have information to contribute to the profile of William Biddle. This is what I can add:
He was born in 1630
These are the sources I am using:
Colonial Families of the USA, 1607-1775, page 92

Should I contact one of the pre-1700 projects or know about any style guidelines before proceeding? Thank you!
Just to note: the baptism mentioned took place in Birlingham rather than Worcester as in location field. It was on 10 March 1623/4. (and unlikely to be 4 years after birth)
