I use census plugin for recording census and tax lists.
There is a bug in census gramplet. If your census.xml contains special characters like German äöüß then you cannot choose any source from dropdown. This could even happen with translation.
add line 59 like follows so to omitt translation.
57 # The key of the data item in a source to define it as a census source.
58 CENSUS_TAG = _('Census')
59 CENSUS_TAG = 'Census'
In census.xml you the "<size>25</size> " works. but it seems person is always first place in a row, what ever you write in census.xml.
Another improvement could be to not only add a person and a census event, but also place-event.
