Introduction Introduction

What is the Pemberton DNA Project? How does genealogical DNA work? August 2010: Project started Feb 2011: George P Cheshire, 1685, DNA proved Mar 2011: George Victor P same common ancestor Mar 2012: Huguenot P’s DNA identified Sept 2012: New Zealand ffrench P’s DNA Sept 2013: Pennsylvania P’s DNA ??? Sept 2014: Pemberton’s Previous Surname ???

Proving George P’s 1685 DNAProving George P’s 1685 DNA

Feb 2011: Three P’s with known MRCATheir 3 tests show one different marker eachMode is established (2 out of 3 sets the mode)The common ancestor’s DNA is the modeOnly the mode could produce the 3 resultsCheshire George’s 1685 DNA is provedQuestions?

This chart shows the 4 markers that differ from the mode; one in each of four samples.

Robert’s profile is identical to the mode!

Cheshire George Victor’s DNACheshire George Victor’s DNAMarch 2011: Test of George Victor of Tarvin, Cheshire, shows that he also descends from the same George or one of the latter’s ancestors. The fact that he only has one marker different strongly suggests that the MRCA is not very many generations back. Documentary research is now rightly focused on this same George, 1685.

The ffrench-Pemberton BranchThe ffrench-Pemberton Branch

John Stuart Pemberton of Waikato, New Zealand: son of Stuart ffrench P, Frederick ffrench P, Charles ffrench P, and Robert P

"This family is descended from a Robert Pemberton (1787 - 1877) concerning whose parentage there was always a mystery.” R. C. B. Pemberton, ca. 1912

DNA from this line is waiting at the laboratory at Family Tree DNA

The ffrench-Pemberton BranchThe ffrench-Pemberton Branch

Email from John Stuart P, August 1, 2012: Some details of Robert Pemberton: 1) Foundling Hospital, Coram's Fields, London,

UK. Family history suggests he was given the name of one of the Foundling Home's Directors.

2) Foundling Home Nursery Book, 1759-1812, No. 4, records his number as 18061 and the fact that he was sent out to nurse on 8 May 1788 and returned on the 7 October 1793.

3) At about 14 years of age, he was apprenticed to Edward Southbrook to be "instructed in household business till the age of 21 years"

4) Robert was [ born 1788 and] adopted in 1801 by Edward Southbrook and Georgina Charlotte Augusta Southbrook (nee Denoyer).

Was he really a Pemberton? (Yes, of course.) Does his gggggrandson’s DNA match other

Pembertons?

Finding the Ancient P’s DNAFinding the Ancient P’s DNA

1. Identify the Pemberton branches2. Look for matching DNA in other

surnames that are known possible ancestors of the Pemberton family

3. De Windle, Orrell, Villier, Tratford, ??

SummarySummary

DNA is a powerful research support toolDNA tests can be cost effectiveEleven tests show only two branchesMore tests are needed to assure the

identification of the major family branchesTests are needed from Pennsylvania lineTests are needed from other known linesThe Pemberton DNA Project General
