I can add a father to the profile of Johann Jacob Altman. This is who I can add:Johannes Altman 1650-1721
These are the sources I am using: Hans Wilhelm Altman's descendants, Ancestry.com,which is using some type of world wide family tree that I cannot verify.
Should I contact one of the pre-1700 projects or know about any style guidelines before proceeding? Thank you! I would like to dig into this line further. That tree has specific dates and information but I do not know where it comes from or how to verify it. Help? Thanks.
