Joan and three of her siblings have had their DNA tested which has enabled the Visual Phasing technique to be used to map John's DNA back to his 4 grandparents. Through these tests both the maternal and paternal lines have been confirmed back to their parents Edward Roberts and Mona Murphy.
The paternal line is confirmed back to her fifth great grandparents John Lee and Elizabeth Higgs.  It has subsequently been confirmed that an additional segment on Chromosome 7 belongs to John Lee.  For details of further DNA confirmations on the paternal ROBERTS line please click here.
