About the study

The THOMERSON one-name study is about genealogy and putting the 'flesh on the bones' of our ancestors with this surname in the sense of identifying where they lived, what they did, the hardships they suffered and the pleasures they enjoyed. It aims to pull together all connected strands of the family worldwide and to identify and inter-link as far as possible those strands that currently exist outside of the main family tree. It seems probable that a name change from THOMASON to THOMERSON started the name and this has occurred at least once in the UK (in Essex), with a possible second occurrence in Scotland. In the USA, immigration and further changes of Thomason to Thomerson seem to be responsible for the presence of the family name (this research is work in progress).

My interest in the Thomerson name came about when my mother related a much-repeated assertion from her mother that if she were ever to meet another Thomerson, then that person would be related to her in some way. My mother continues the story with a description of the time that she met an airman named Thomerson in East Africa towards the end of World War 2. She was a nurse and treated him for a few days for burns received when his plane crashed. She remembers writing a letter for him to send to his mother, his hands being badly burnt. What she never found out was whether or not that airman was related to her. In 1990, this was the question that challenged me.
I was able to find that airman, living in Canada. He was related to my mother - they were fourth cousins - and was able to meet my mother again when he next visited the UK. Unfortunately, he didn't remember my mother at all!

I am very happy to receive enquiries from anybody about the Thomerson name and it is my intention to respond in under a week (usually 1 or 2 days) with the only exception being when I am on holiday. Please e-mail me or contact me via ordinary mail.

Variant names

The name under research is THOMERSON. Research is extended to Thomason where this name links into the family, but all Thomasons are not included in this one-name study for the simple reason of volume of information.

Name origin

The origin of most UK occurrences of the name can be traced to the area around Saffron Walden in Essex and this includes branches of the family that have emigrated to the USA, Canada, South Africa and Australia.
Also, in the USA, there seems to be a clustering of the name in Kentucky and Texas with some occurrences in Indiana and North Carolina; it is probable that the name started there independently from the UK and further research is on-going. Any offers of help gratefully received.

Thomerson probably came about as 'Thomason' pronounced with a regional accent and recorded by someone who was not a native to that accent.
Thomason almost certainly means 'son of Thomas'.
There is a belief that 'Thomas' comes from the Aramaic (one of the Semitic languages) term for 'twin.'

Historical occurrences of the name

The Thomerson name appears very infrequently in the media and historical contexts; probably this frequency is consistent with the general low frequency of the existence of the name.
That said:
Tim Thomerson is a current USA actor of moderate fame (see who has appeared in several films and TV programmes including 'Baywatch', 'Ally McBeal' and 'Sabrina, The Teenage Witch.'
Carol Thomerson is well know for her upholstery books as any internet search will identify.
Jamie E. Thomerson is professor of biology at Southern Illinois University at Edwardsville (USA). He has published numerous articles on neotropical freshwater fishes.
Several Thomersons in the UK have been builders and were responsible for building a large number of houses in Hackney and Bethnal Green. Others were architects, cabinet makers and zinc workers to mention a few.
