Looking for a plugin that is a custom table

I’m newish to WordPress but I’m looking for a plugin that allows me to create a custom table full of people’s names and other attributes.

This is for a PTA site for our school where we want a list of parent names, their kids names, and their kids teachers names. They want a global search so you can look someone up by their kids, the parent’s name, or their teachers name.

I’m currently using Participants Database which is close to what we want but it doesn’t have a global search feature. You need to select each field one at a time (ie: you need to select a teacher’s name and then search rather than entering the teacher’s name and any record that has that in it [in any field] will appear.

Anyone know of a plugin like this?
