A good You Tube presentation on Big Y 700, referenced by Paul in a message, at
In genetic genealogy, the most recent common ancestor (MRCA) of any set of individuals is the most recent individual from which all the people in the group are directly descended. This came up in the presentation and it is said the best evidence from recent Family Tree DNA’s research is about 90 years for each mutation we share. In the case of Janine and her dilemma about the Stagpoole/Stack surname this date of 5 mutations x by 90 years puts our common ancestors around the mid 1600s. This was a time of great upheaval in British history where your surname mattered in identifying your political and religious position (as it still does of course). See for an example the restoration of Charles The Second to the throne and a little later the rise and fall of the Stuarts https://en.m.wikipedia.org/wiki/Stuart_Restoration
