Hello!! I will have to dig up the old paperwork my niece helped me with in tracing our roots. It's not very extensive. But...is there a way I can see what you've done and I could ask my Dad to try and verify? Perhaps we can find a connection? There are some Airhart's in Florida who are related to me (brother, niece, nephews, Aunt) in case you found them in your research. It would be fun to see if we are connected!
