I have a tree with lots of medieval, and even mythical, figures, in which there are a lot of people who are siblings with unknown parents. This means that they are connected to a parent family, in which both parents are empty. When I select the families view, I can create a filter for all sorts of …

Create a 2 custom filter for Families Father missing (Invert RegEx for any Father ID) Mother missing (Invert RegEx for any Mother ID) Then a Families filter that finds both: [image] custom_filters.xml <?xml version="1.0" encoding="utf-8"?> <filters> <object type="Family"> <filter name="…

I have several (real) people that I know the sibling but not the parents. I tag the Family with the apt named “Related Siblings (unknown parents)” tag. I make the tag Red so in the family list I know why both parents are blank. Note: Two of these are endline ancestors so when I do a search for rel…

Yes, that’s a smart one. I tried searching for empty IDs wirh the ^$ regexp, but that didn’t help, and the inversion that you use here, of a positive match on any ID, may probably solve the problem here too. Searching for end of line persons won’t help here, because I only want to select the famili…

[image] ennoborg: Yes, that’s a smart one. Not smart. I fumbled through a dozen filters where the logic fit but failed to produce results. This was pure trial and error. As always, a good Regular Expresssions “NULL” search eluded me.

[image] ennoborg: I only want to select the families that have no parents, and 2 or more children. I guess the top Custom Filter needs an additional Family Rule for that last ‘2 or more children’ parameter: Family with <count> of child where Number of instances:="1";Number must be:="greater…

I sorted by Father in the Family view then tagged the records.

OK, I thought that it was smart, because you reversed my thinking, where I tried to find empty IDs with the ^$ regexp. I can make your example a bit simpler though, by replacing the expressions with a single dot. That works, because that single dot matches with any character, and the regexp search …

Your filter works and it agrees with my tagged families. To find each parent without ID’s, I tried it with just a period . in the ID field, Used regular expression then invert the results. The . indicates any single character (letter, number, or anything) It returned the same results as the (.|\s…

[image] DaveSch: It returned the same results as the (.|\s)*\S(.|\s) conditions. Strangely, the (.) was very slightly slower than (.|\s)*\S(.|\s) Ranged from 3.17 to 3.83 seconds to find 90 families in 18,688 families
