Welcome to WikiTree!
Here's a link to the Pre-1700 Profiles help page. Coordination with any associated projects and reliable sources are required for creating/modifying pre-1700 profiles.
If you can add geographic location information to your G2G post, it will likely be helpful for determining which project(s) may apply for the pre-1700 profile(s) in question. Also family trees are not considered adequate sources for pre-1700 profiles.
It's also important to ensure that a profile doesn't already exist for an individual before creating a profile. This is especially true of pre-1700 profiles as the ancestor is likely to have many descendants and may already exist in WikiTree.
