Agreed, that it looks like it should be chronological order. But this guy had four different spouse relationships...which one has the child you are looking for? His are mostly progressive, one after the other. But, dare I even bring up polygamy with multiple simultaneous spouses and many children that were born to those families? Figuring out which child is the error could take quite a bit of time. A hyperlink or name of the child that generated the error message would be of immense help in these situations. Hyperlink would be best, since you would still have to search through all the different families to find the child you are looking for even if you knew the name. AND they often used similar name combinations!
