Advice before editing this pre-1700 Tellam profile?

Question

I have information to contribute to the profile of Avis (Tellam) Blewett. This is what I can add:

• Children and husband

These are the sources I am using:

• Marriage

• Source Information

  Ancestry.com. England, Select Marriages, 1538–1973 [database on-line]. Provo, UT, USA: Ancestry.com Operations, Inc., 2014.

  Original data: England, Marriages, 1538–1973. Salt Lake City, Utah: FamilySearch, 2013

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