Advice before editing this pre-1700 Bullinger profile?

Question

I have information to contribute to the profile of Johann Balthasar Bullinger. This is what I can add:

• Missing data and corrected data

These are the sources I am using: 

• Gw.geneanet.org (Hans Balthazar Bullinger b: 02 Jun 1652 - Zurich; d: Aug 1720.

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

Answer 1

Family trees are not encouraged for pre-1700 profiles, do they cite actual sources? If so, those records are what should be cited.
