Title: Autosomal DNA & One Name Studies

Speaker: John Titterton

As the registered researcher of the Titterton One Name Study, John is
researching all instances of the name Titterton. He has established about 30
different Titterton family trees but there are a number of brick walls
stopping them being connected together.
There are three types of DNA testing;
· that going back in the female line (mitochondrial DNA);
· that going back in the male line (Y Chromosome DNA)
· that going back in all lines (autosomal DNA).
One might expect that the Y chromosome DNA tests would be the best one
to help a One Name study. John was contacted by a complete stranger with
a Titterton grandmother. Their autosomal DNA test had three Titterton
hits which did not connect to the grandparent nor to each other. The talk
discusses how he was able to make connections between different Titterton
branches using these autosomal results. He was then able to break down
brick walls.
