Introduction

This is the current iteration of an attempt to keep track of Wikitree's coverage of the core of the European higher nobility (previous versions were posted on G2G in January, February, and October 2020). In brief, it should theoretically be possible to identify most if not all 2,046 ancestors in the first ten generations of the pedigree of most reigning European monarchs, pretenders, and heads of mediatised houses. Rarely do we have full coverage of those ten generations on Wikitree, but we're improving! See below for details and scroll down to the final comment for a summary of where we are as well as some interesting statistics generated by the project.

Also included are statistics for the population of the first twenty "circles" of each monarch or head of house (see the 100 Circles Project for more details on what this means).

How this works

The process of identifying the current coverage in Wikitree is very simple. At each update, the most recently deceased head of the monarchy/principality/county in question is plugged into the Brickwalls app (https://apps.wikitree.com/apps/nelson3486/brickwalls/) and the statistics generated there are used the basis for the entry. To give a sense of progress, statistics from the last update are given in brackets, and to guide anyone interested in making contributions, the three most recent ancestors for whom one or both parents are unknown are also listed.

Since the annexation of Georgia by Russia in the early nineteenth century three different branches of the formerly reigning Bagration royal family have claimed the throne. The Mukhrani and Gruzhinsky claimants are given below; the Imeretinsky claimant and his ancestors have yet to be added to WT.

Mediatised Houses

For those unfamiliar with the term, "mediatisation" refers to the political process by which formally "immediate" nobles - i.e., those who were subject only to the Holy Roman Emperor - instead became vassals of "immediate" states. This was an ongoing process throughout the early modern period, but is particularly used with reference to the mass loss of sovereignty caused by the Reichsdeputationshauptschluss of 1803 and the Treaty of the Confederation of the Rhine of 1806, side-effects of the larger transformation of Europe caused by the Napoleonic Wars. Traditionally, those houses mediatised in this period were considered equal in birth to reigning families, meaning that marriages between the two would be considered equal rather than morganatic. As such, their ancestry tends to derive from the same genetic pool as the reigning houses covered above and they have been included here accordingly.

Data on these houses is being added gradually as time permits with progress being slow in part due to the number of heads of house not currently represented in WT.

Summary

Archduke Otto of Austria is the first monarch to pass the 90% threshold with 92.13% of the first ten generations of his ancestors recorded in Wikitree as of 12 March 2021. Following closely behind, Carlos, Duque de Calabria (86.51%), Philipp Albrecht, Herzog von Württemberg (85.73%), Mihai I of Romania (85.39%), Maria Emanuel Markgraf von Meißen (83.87%), Manuel II of Portugal (83.63%), Albrecht Herzog von Bayern (80.21%), and Jean, Grand Duc de Luxembourg (80.06%) are now all over 80% complete and many more individual ancestries fall in the 50-70% range. Most dead-ends are now in the eighteenth century, save for a few notable more recent blocks, such as the ancestors of the Montenegran royal family who appear in several pedigrees.

While this figure is subject to considerable change, at present Ferdinando, Duca di Castro and claimant to the Sicilian thone, is the most inbred of the individuals listed here with an impressive 84.85% of his ancestors appearing more than once in his pedigree.

In the language of the 100 Circles Project, George VI of Great Britain has the most fully populated circles with a cumulative total of 10,202,004 in his first twenty circles. He is followed at some distance by Louis Ferdinand Prinz von Preußen with 8,646,823 and Alfonso, Duc d'Anjou with 8,007,129. At the other end of the spectrum, Petr Bragation-Gruzhinsky, claimant to the Georgian throne, has merely 20,945 individuals in his first twenty circles. Can we bring him closer into the world tree?

Are there any individuals/states you'd like to see added to this list? Do you have corrections to make? Let me know in a comment below.
