I also find Duffy’s in Napa, CA. Apparently Thomas M. McLaughlin and Phillip Duffy were childhood friends in Newport, New York. Thomas’ and Phillip’s wives were sisters. Ellen and Catherine Maxwell were from Newport, New York, having emigrated from Ireland. They went onto Austin, NV, and eventually moved to Napa, CA, where they spent the rest of their lives.
So are these two Duffy family groups related? I’m not sure but thought I’d post about it in case a Duffy is interested. I am only related to the Duffy’s by marriages in my family tree. I seem to have some information about the Duffy’s for both of these family groups. I have some information in the “34 page document” and I have some papers in “the box” that my mom brought me originating with a Malloy of Napa, CA.
A funny thing happens when you visit Ireland, too. In my case, I found a Duffy who is married to my Flanagan relative. It is less likely that they are of the same Duffy line. What a small world.
