I poked around on Google Maps last night and notice that the further east you go, more towns ended in 'tai'. I'm kind of thinking it might be more east as this was his last location before coming to America. Sort of makes sense? I want to check a few other sites that have older maps-might find it but might not and again, more likely than not, it's a spelling issue. Since we have about 7 fairly major variations on my grandfather's last name, that wouldn't surprise me!
THanks for your interest-I'll post whatever I find out.
