For this week's great-grandparent challenge, I have chosen people who were involved in the development of soft drinks, pops, or sodas. Most of these people are not connected to the main tree, and none of them have a full set of great-grandparents listed on WikiTree. In order for us to add a list to the Relationship Finder Quick Links page, each person on it needs to have at least one line going back as far as their great-grandparents (and preferably all eight great-grandparents).
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 soft drink pioneer, and add a new great-grandparent, please post a message here, so we can keep track of how we're doing.
If you manage to connect one of the soft drink pioneers who are not already connected to the main tree, you can count that connection towards the Connectors Challenge, if you're taking part in that. (And, if you happen to find an additional connection path for a soft drink pioneer whose family you're working on, that makes them all the better as a relationship finder!)
If you run across an unsourced profile which is already on WikiTree and add one or more sources to it, you can count that source towards the Sourcerers Challenge, if you're taking part in that. If you can add sources, photos, or biographies, add siblings, children, aunts, uncles, etc., or improve the profiles of these people or their family members in other ways, so much the better!
