Purpose of site

The purpose of this site is to collect and publish prosopographical information about ancient Roman Republican and Imperial senatorial and equestrian families. The Eastern dynasties have been added to show the relationships to Roman families and other Eastern dynasties. The families are shown as genealogical family trees, a stemma.


The periods covered are both the Republican from 509 BC until 31 BC and the Imperial until 284 AD, when Diocletian became emperor. It includes stemmata (family trees) of the Roman senatorial gentes (families), and also includes equestrian members.

Status 30th January 2021

The project includes 357 stemmata, incl. 19 stemmata for Eastern royalty, plus 49 files on legions. Note that the earlier stemmata from 2014-2015 still need major updates, in some cases total rework. Versions prior to November 2013 have now with one exception ("F_various" from 2010) all been updated. In general the newer the date the more detailed information and references are included plus an extended header section. I am also gradually converting font from Arial to Times New Roman.

Guidance to the stemmata

Please see the Guidance topic for information on the structure and details of the stemmata.


The first phase is to collect the raw prosopographical information.
When all have been entered in more or less raw format, a second pass of analysis will structure the genealogical tables with information on the confidence level of the relationships, entries will be updated with information from sources available since the Realencyclopaedie and PIR have been published, references to relevant articles and notes with information on the individuals will be added.

Please be aware that many of the geneological connections in the stemmata are uncertain and can be disputed. I have in general tried to be conservative and not make undocumented assumptions about possible connections. Often several variants are possible. Fresh evidence, typically from new inscriptions, can often correct a stemma or indeed overturn old theories.

The author of this site is Christian C. Strachan. I graduated from the University of Copenhagen in 1980 with a Masters Degree (cand.mag.) in History and a bachelor degree in Political Science. My thesis was a "Prospographical Analysis of Political Adoptions during the Roman Republic". My continuing interest in Roman Prosopgraphy is the main reason for this site.

I also enjoy astronomy/cosmology. Below are two nice pictures.
