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
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.

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.
