I have received expressions of interest from 25 members of the Tonge family
over the last two years, with ancestral roots in Lancashire (11) and Kent
(5) and others. Of those 25 people, 11 have sent DNA samples to the
Success! The DNA project has succeeded in
satisfying one of it's initial objectives, which was identifying a genetic
fingerprint for the Tonge family of Bolton. Five people called Tonge,
all with ancestors hailing from the Bolton area, but with no family tree links
in the last 200-300 years, all have matching DNA. That means that they
must all be descended from a common ancestor.
Thanks to everyone who has responded so far. If you are interested in
participating then please don't hesitate to contact me at
How can DNA help in genealogy?
The Y chromosome is passed from father to son unchanged, except for a
mutation about every 500 generations. Testing the Y chromosome will provide
you with a genetic finger print consisting of 12, 25, 37 or 59 numbers. By
comparing this finger print to others with your surname, you can determine if
they are related.
In line with most other surname DNA projects, there are several objectives,
and they may change over the life time of the project, depending on the
specific interests of the participants.
To prove, or disprove, the theory
that the different Tonge families originating from various areas of England
(Lancashire, Yorkshire, Kent, Lincolnshire etc.), are in fact entirely
separate families, not genetically related. That each family took
their name from a local place called Tonge, of which there are at least six

Findings so far
The haplogroup of the project
participants so far is R1b1. This is the most common haplogroup in Western European
populations today. It is believed to have originated in the peoples who took
refuge in Iberia during the last ice-age. At the end of the ice-age (10-12K
years ago) humans from this region migrated up the Western coast of Europe
and partly into central Europe.
Five of the participants cannot be shown to be related through paper
records, but the Y-DNA test shows that they probably are related, although
fairly distantly. The results suggest that they probably share a
common male ancestor within the last 350 - 800 years.
Five participants have the marker
value DYS390=23. A number of studies have suggested that this value is
indicative of "invader" origins from the Teutonic countries, maybe
therefore Anglo-Saxon or Danish in origin.
Research looking at
the geographic frequency of DYS390 = 23 combined with DYS391 = 10 show that this
genetic signature occurs most frequently in South East Germany, and is not
found frequently in Sweden or Norway.
