Claas Claasen - Sources for this new area on the tree

Irene Elisabeth Visserman this is a new and very interesting area you are adding to the tree. Extending the Slave tree is just what we need, so that's great - thank you. Some of the profiles appear to be duplicates of profiles in other places on the tree, & so are causing mismerges. Can you give us your sources so we can figure out together whether new information means the old placings are wrong.
Catharina Van de Kaap; Aaltje Cornelisz, b4 SM/PROG; Armozyn Claasz Leij, SM; Adriaantjie van der Kaap; Catharina Van de Kaap are other profiles that could be duplicates just with a different mother.
