Whatever Geni means by the sex mix-ups above, I believe the connection from Agnes to Jeanne should be:
Agnes Le Couteur, (wife of Louys Estur)
→
Michel Le Couteur
his father →
Philippe Le Couteur
his brother →
Jean Le Couteur
his son →
Jacques Le Cousteur
his son →
Josue Le Couteur
his son →
Josue Le Couteur
his son →
Jeanne Le Couteur
his daughter
It seems to be right in the tree, in spite of the above wording.
I've noticed wrong sexes in other parts of Geni, so one has to look out and correct them. The above gobledegook about Luoys Estur being a brother of Agnes is worse than that however. Where someone appears as a spouse of a cousin, say (Josue, Jeanne etc.) is it your preference leave them appearing more than once in a tree, or to try to merge them (with consequential problems of connecting lines)? Is it a Geni 'first time' default to keep them separate? I think I favour that, to avoid clutter.
