Baldwin III ruled briefly as joint count with his father Arnulf I, but died before his father. Count Baldwin's name appears in lists of abbots of St. Bertin [Monumenta Germaniae Historica, Scriptores series, 13, 391, 607], and he would appear to have held that office for a short period before his death. [Ref: Henry Project]

Possible illegitimate son (status uncertain):
Ascelin (Azelin) or Albert de Tronchiennes, bishop of Paris, 1016-1018.
The History of the Bishops of Cambrai states that Ascelin (or Albert, as he is called in some sources) was an illegitimate son of count Baldwin of Flanders. [Gesta Episcoporum Cameracensium, MGH SS 7, 448]. If this is accurate, Baldwin III would be the only count of Flanders named Baldwin who would make a chronologically feasible father for Ascelin. [L
