Nev, The "UDF List" Plugin reports "Uncategorised Data Fields" due to malformed GEDCOM. The "Show Project Statistics" Plugin provides a statistical report but also identifies unusual data entries. There is nothing malformed in the GEDCOM it is just that some data entries are so rare they are worth highlighting. A Family Record with only Children is perfectly valid GEDCOM, and identifies siblings where the parents are unknown, but it is unusual. Similarly, it is valid GEDCOM for an Individual to 'marry' the same Spouse twice, but the Plugin reports it as exceptional. There are many other valid GEDCOM entries that the Plugin lists as exceptional and worthy of review. I would be interested in what you discover.

I should have added I ran the "Find uncategorised data" tool which found a problem with the GEDCOM but with a 'real' family, and they had 10 children and not 2! We live and learn - I hope! Nev.
