Advice before adding of this pre-1700 Coe profile?

Question

I can add a to the profile of William Coe. This is who I can add:

• Margery Sugg
• Susan
• Elizabeth

These are the sources I am using:

• Robert Coe, puritan; his ancestors and descendants, 1340-1910, with notices of other Coe families : Bartlett, J. Gardner (Joseph Gardner), 1872-1927 : Free Download, Borrow, and Streaming : Internet Archive

Should I contact one of the pre-1700 projects or know about any style guidelines before proceeding? Thank you!

Are you able to find any original records?
Wills, parish records, legal records?
19th and early 20th century genealogies are sometimes reliable, sometimes not.
