Lambert, Count of Hesbaye

Lambert (alive about 700 AD) was the father of a Frankish noble named Robert, who was described in 741 as a "count or duke" in the neighbouring Hesbaye and Maasau regions in what is now northeastern Belgium. No other record about this Lambert exists.

Lambert's own life details and family remains unknown, although it has been proposed based on the use of the names Robert and Lambert that he was the son or paternal grandson of Robert II (Chrodobert II), Lord Chancellor of Francia, and a close relative of his contemporary and namesake, Saint Lambert of Maastricht.

Lambert had one child:


 * Robert, count or duke in Hesbaye and Maasau

Another child has also been proposed, although this is disputed.
 * Rotrude, married Charles Martel. Grandmother of Charlemagne.
