They moved into the warehouse after they sold their place in Siloam Springs last year (or late 2018? It's been a while). They never bought a new house.
Garrett was ill. We know Josie didn't travel to Ohio, and I doubt family brought Garrett to AR after Josie returned home. There was only about a two month window.
He might have met Jordyn, but I'd say that is it.
I don't know if Garrett met all 19. I think their trip to Ohio was pretty early in the series.
eta He died in mid 2010. I doubt he met Josie, who was still very fragile. And Garrett had Alzheimer's, IIRC.
