My colleague Lisa Little was in a similar situation to yours, and again, through diligent research and some targeted DNA testing, was able to find out at which generational level the DNA Switch occurred.

From an emotional POV, it was not near and dear to my heard! lol Finally, through diligent paper research and DNA testing, I found the genetic Y-DNA break in my line.

Our Holt line (Nicholas) which is the MA/NE line with many descendants is an exact DNA match to one of the Pennington lines linked to Lancashire. If you could share the details and or documentation of the incidents you mention, it could provide extremely helpful clues!

FYI The ISOGG Wiki entry at https://isogg.org/wiki/Non-paternity_event has a very long list of possible SDS causes as well as pointers to various incidence rates and studies. Not surprisingly the estimated rate varies considerably across the ages and cultural and social norms. <br /><br />There are many anecdotal cases of SDS in Dave Vancehttps://www.blogger.com/profile/10823699447442510111noreply@blogger.comtag:blogger.com,1999:blog-5443730660032753146.post-42101972416363523222018-07-15T01:16:55.028+01:002018-07-15T01:16:55.028+01:00Interesting analysis, John.

Analysis in the Manx Y-DNA study see http://www.manxdna.co.uk/MYDNA5%20doc8.pdf. shows an incidence of NPE/SDS of around 0.5% per generation or ca 12% in the tested male population. This is based on a sample size of over 470 men tested so far. <br />Cheers<br /><br />John Creer John Creerhttps://www.blogger.com/profile/09333402270426243683noreply@blogger.comtag:blogger.com,1999:blog-5443730660032753146.post-38034585738097359532018-07-14T21:50:03.770+01:002018-07-14T21:50:03.770+01:00Great article, may we reuse on site Worldwide Ance...Great article, may we reuse on site Worldwide Ancestry Finders?

One being my Grandfather was given his mothers maiden name, his mother then married (twice) and he still retained his mother's maiden name.

I think this was as a result his wife's (Mary Anne) lobbying. She came from the same Irish background and you can see her parent's family switching from RC to CoE through the parish registers and also changing the mother's surname pacohttps://www.blogger.com/profile/13011476552820075582noreply@blogger.comtag:blogger.com,1999:blog-5443730660032753146.post-39115226673275539602018-07-13T19:27:16.792+01:002018-07-13T19:27:16.792+01:00Many thanks!
