Every one of the below Anstey sub-branches are thoroughly documented in the book:
‘Anstey: A Complete History From the Norman Invasion to World War One‘
which contains over a thousand Anstey biographies, as well as a plethora of research and statistics, including an analysis of precisely how each sub-branch fits (or does not fit) into the pedigree descendent from Hubert de Anesti, the 12th century originator of the ‘Anstey’ surname.

Given that almost all ‘Anstey’, Ansty’, ‘Anstee’ and ‘Anstie’ alive today (with the exception of ‘Anstey evolved from other surname‘ sub-branches), are connected, sharing a common 12th century origin, all ‘Anstey’, Ansty’, ‘Anstee’ and ‘Anstie’ by definition belong to multiple ‘Anstey’ sub-branches. It also follows that the closer two Ansteys are related to each other, the more their respective multitude of Anstey sub-branches will overlap.
As such, when conducting ‘Anstey’, Ansty’, ‘Anstee’ and ‘Anstie’ genealogical research it makes sense to focus on principal, major and minor sub-branches, and connecting them together like blocks of lego. For example, I can trace my Anstey ancestral line back centuries by connecting together the following Anstey sub-branches:
- I am a Stoke Gifford Anstey (a major sub-branch);
- the Stoke Gifford Ansteys are a sub-branch of the Dyrham Ansteys (the principal sub-branch of the South Gloucestershire Ansteys);
- the South Gloucestershire Ansteys are a sub-branch of the Dulverton Ansteys (the principal sub-branch of the South West Peninsula Ansteys);
- the Dulverton Ansteys are a sub-branch of the Cambridgeshire Ansteys of the 1400s and early 1500s;
- the Cambridgeshire Ansteys of the 1400s and early 1500s are a sub-branch of the medieval Edmonton Ansteys; and
- the medieval Edmonton Ansteys are part of the medieval Anstey pedigree commenced in 1143 by Hubert de Anstey, the originator of the ‘Anstey’ surname.
So every single one of the 150 or so Ansteys alive today who can trace his or her direct ancestral line back to John Anstey (SG 1), patriarch of the Stoke Gifford Ansteys, is a ‘Stoke Gifford Anstey’, regardless of where they live in the world today and regardless of whether they have even heard of Stoke Gifford!
We have classified all ‘Anstey’, Ansty’, ‘Anstee’ and ‘Anstie’s into one of 8 principal sub-branches, which split into about 50 major sub-branches, and then around 75 minor sub-branches of the major sub-branches, which seem to be three nice round numbers. They are:
