OK Thanks. I changed that and I still do not see a few entities.
But I think this may be functioning correctly. It seems that spouses ancestors do not show. From the main line, siblings show, then all the siblings children, grandchildren etc. Also the spouse shows who started all those children. But it does not go back up through the spouses parents. It looks like a function of how it works. Probably people who have been doing this a while are rolling their eyes at me. Anyway as I wanted them on, regardless of convention and I can get the missing ones displayed by centreing on anothor entity I can just cut and paste pfds togather.
Thanks.
