Guild of One-Name Studies
One-name studies, Genealogy
The name is more frequent in the USA where, based on census data from 2000, there were 6888 individuals (4257 Middlebrooks & 2631 Middlebrook). This is about 1 in every 39,000 people.
In the USA, the name is mostly concentrated around the south-eastern states - particularly Georgia, Texas & Alabama. The Middlebrooks variant is especially strong in Georgia, where over 50% of individuals from the 1940 census were found.
Some of these data can be accessed from my project website at: Middlebrook Databases.
