Hey, Leo! I have been eagerly awaiting your additions to the profile.
You created profiles for his parents and you connected those profiles, but there is no text in these profiles to document what you found in the Dutch records, and the source citations that you added to the profiles for the parents (example: "18 May 1645, marriagebook LOPIK") do not contain enough information for someone else to find the source. See Help:Sources for WikiTree generic advice on citing sources. For pre-1700 profiles like these, it is particularly important to provide in-line citations or footnotes to show sources for the specific facts and to use sources that we consider to be reliable. It appears that you have found Dutch church records and similarly reliable sources, but we do need to know what exactly you found.
