Here's the 1920 Federal Census record from Roanoke Rapids, Halifax, NC. The spouse looks more like Gergie Anna than
Georgia Anne and that is how it has been entered in the database. Children are
Irwin McK. age 5, William age 3, Katherine age 3mo and Elizabeth age 3mo. Another set of twins is rather interesting. This census shows William H. Clary as a Machinist at a cotton mill.
I'm at a dead-end going up the tree, though. Even if he is the son of Jonathan, I'm not finding earlier records for him in the databases I have access to. I don't see any of these names in OneWorldTree either so this may take some legwork to confirm and flesh out.
Hope some of that helps get you started.
