Advice before adding of this pre-1700 van der Have profile?

Question

I can add a to the profile of Agatha Adriaens van der Have. This is who I can add:

• mother Cornelie Anthue Colen birth born 1498 in Middleburg, overl. Brewershaven   1547, dr van Mr. Joos van der Hooge, mayor of Middleburg, and Adriana van wissekerke.
• Title : Baljuw- Baliff - court officer or keeper of a Royal castle.
• Death 1539 Zeeland, Netherlands

These are the sources I am using:

• Roots tech through family search
• Collaberations 
• research doen by Edwin Hamelink, Netherlands

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