He was the fourth son of Mieszko I of Poland, the third born from his second marriage with Oda, daughter of Dietrich of Haldensleben, Margrave of the North March.
Nothing is known about his early years. After Mieszko I"s death (25 May 992), the war began between Bolesław I and his half-brothers for the paternal heritage, a dispute which according to some historians lasted only a few weeks, and according to others, only finished in 995. Lambert"s further fate is unknown.
Previously he was identified with Lambert, Bishop of Krakow (d 1030), but now this identification is contested.
