A French Wikipedia article Liste des seigneurs de Picquigny names Adèle (or Odile) as the wife of Guermond or Eudes de Picquigny, and the mother of four sons;
No dates are mentioned for Adele of her husband, but given the eldest son was born about 1040-50, a birth date of about 1025 for Adele is possible.
However although the Wikipedia article does have sources, none are cited for the information about Adele and her family, and her existence is possibly doubtful.
