I am still on the search for which genealogy exactly that the family is referring to.I have stated several times that it is confusing for several reasons. First, the names Baldwin, Godfrey, and Reginald appear in history through several family lines. The kings of Lower Lorraine and Metz are the only ones of concern to us oh yes, and the kings from Boullion, which is in Belgium and right on the border but once considered part of France and blended with people from Metz.....they are all cousins or related in some way.. all from the same region. The name des Marets comes from Metz...this is why all the confusion arises.
Here is a link to the history of Metz and of some of these kings that directly concern our search for the bloodlines of the First Kings of Jerusalem during the First Crusades:http://en.wikipedia.org/wiki/Metz
Metz is the capital of the Lorraine region and prefecture of the Moselle department. Located near the tripoint along the junction of France, Germany, and Luxembourg, Metz forms a central place of the European Greater Region and of the SaarLorLux Euroregion. So, Metz is a fellow member of the QuattroPole union of cities, along with Luxembourg City and German Saarbrücken and Trier.
A Celtic oppidum, an important Gallo-Roman city, the Merovingian capital of the Austrasia kingdom, the birthplace of the Carolingian dynasty, a cradle of the Gregorian chant, and one of the oldest republics of the common era in Europe, Metz has a rich 3,000 year history. The city has been steeped in Romance culture, but has been strongly influenced by Germanic culture due to its location and history. A basin of urban ecology, pioneered under the leadership of people like Jean-Marie Pelt, Metz gained its nickname, The Green City, boasting over 37 m2 (398 sq ft) of open ground per inhabitant and the city's historic downtown also displays one of the largest commercial, pedestrian areas in France.
Metz possesses one of the largest urban-conservation area in France covering 162.9 ha (402.53 acres) and more than 100 buildings of the city are classified on the monument historique list. Because of its tremendous historical and cultural background, Metz benefits from its designation as a town of art and history. The city is home to some world-class venues such as the Arsenal concert hall, the Centre Pompidou-Metz museum, and the National Opera of Lorraine (along with Nancy Opera).
A historical Garrison town, Metz is the economic heart of the Lorraine region
In ancient times, Metz was called Divodurum (meaning Holy Village or Holy Fortress in Latin), and was the capital of the Celtic Mediomatrici. The abbreviated name of this tribe, Mettis, gave rise to the name Metz. At the beginning of the Christian Era, the site was already occupied by the Romans. Metz became one of the principal towns of Gallia, more populous than Lutetia (ancestor of present-day Paris)Though the first Christian churches were to be found outside the city, the existence in the 5th century of the oratory of Saint Stephen within the city walls has been fully proved. In the beginning of the 7th century the oldest monastic establishments were those of Saint Glossinde and Saint Peter. Since King Sigibert I, Metz was frequently the residence of the Merovingian kings of Austrasia and the reign of Queen Brunhilda in particular imbued the town with great splendour. The town preserved the good-will of the rulers, when the Carolingians acceded to the Frankish throne, as it had long been a base of their family and one of their primal ancestors, Saint Arnuff, as well as his son Chlodulf, had been bishops of Metz. Emperor Charlemagne considered making Metz his chief residence before he finally decided in favour of Aachen.
This link has a list of the Dukes of Lower Lorraine, and several kings....these form the foundations for the Des Marets family and for those who led the First Crusade (geesh, most of them really were Merovingians and Carolingians)http://en.wikipedia.org/wiki/List_of_rulers_of_Lorraine
