In looking at FMG, “Robert de Say "Picot" must’ve been an adult in 1060. Also, he married an certain Adelize in the sources potpourri PDF I posted. Her Latinized name in FMG shows as Adeloye:
“A charter DATED TO 1060 records the transactions of "Roberto de Sayo qui cognominabatur Ficot et ADALOYE uxori…et…Roberto et Henrico filiis suis" [trans: Robert de Say who is known as Picot and his wife ADELOYE and Robert and Henry his sons] with the monastery of Saint-Martin de Sees in Normandy, signed by "Rogeri comitis, Picot, Roberti filii eius, Henrici filii Picot, Adeloye uxoris Picot"[1050]. [trans: Count Roger, Picot, his son Robert, Henry son of Picot, Adeloye wife of Picot.]
