Maybe we are related to each other and we're both related to Moonie!
The relative I met online is named Barbara Moon Baptista from California. One of her grandmothers married my 8th great grandfather and somewhere down the line her ancestor married a Moon. Distant relation at best. I think they were from a little town called Wendell, mass. just east of Deerfield.
This history is off the top of my head and could be short on the details but I think it's basically right. I find it fascinating.
If you can get close to that town in your search I can get you in touch with her through FB.
