The Genealogica comitum Buloniensium records that "Ermengardis" was mother of "Albertum comitem de Namuco".
He succeeded his brother as ALBERT II Comte de Namur. He founded Saint-Aubain at Namur, as shown by the Fundatio Ecclesiæ S Albani Namucensis which records "comes Albertus secundus, ortus ex patre Lothariensi, matre vero Francigena Ermengarde, nobilissimam Francorum regum prosapiam trahente" as founder of the church.
The Gesta Episcoporum Leodiensium records "bellum apud Rivoniam" in 1048 where "Albertus Namucensis" was killed by "Godefrido duce". 1
