In Bereishis 12:5 we see that Avraham took with him את הנפש אשר עשו בחרן "the soul they had made in Charan." Rashi there comments that "Abraham would convert the men, and Sarah would convert the women, and Scripture ascribes to them [a merit] as if they had made them".
Do we ever know what happened to this convert and what become of him?
