The task is to seek out, source, and add profiles for as many missing great-grandparents as you can find. As you take on a hymn writer, and add a new great-grandparent, please post a message here, so we can keep track of how we're doing.
If you can add sources, photos, or biographies, add siblings, children, aunts, uncles, etc., or improve the profiles of these hymn writers or their family members in other ways, so much the better!
This challenge isn't specifically about connecting unconnected branches, but rather about adding as many great-grandparents as you can find. Nevertheless, if you can connect one of the hymn writers who aren't already connected to the main tree, that would be a big benefit for WikiTree as a whole.
P.S. I'm not a WikiTree Leader, and have no authority to assign points, credit, or anything like that. My intent with these challenges is for them to be a fun little break from whatever you're doing regularly. (Well, that, and preparing lists of different kinds of notables for the Relationship Finder Quick Links page.) There's no time limit, there are no prizes, and if you have fun finding and adding relatives, then you win. (And WikiTree wins in any case, because the more connected profiles we have, the better the tree is for everybody.)
P.P.S. If this challenge intrigues you, and you think you might like to try finding great-grandparents for other notable people so they can be added to the Relationship Finder Quick Links page, you can find other threads in this series on the How to increase a country's presence on WikiTree page.
