I was wondering what anyone's thoughts are regarding R-Z16434 and downstream mutations.

I fall under R-Z18136 which is mostly comprised of Murphys and people who happen to know they are Murphy. I've seen estimates of the age of the MRCA being estimated at about 410 years old on the Big Y Tree, however one of the Murphys has ancestors born in the 1600s that ended up in the Colonies. In any case I am very interested in learning more about them. There is a sibling block to R-Z18136 called R-BY98445 has a Murphy and a Murfee. Very excited to learn more.
