"The souls they made in Charan"

Question: What happened to all of the people that Avraham and Sarah converted? Were they integrated into B'nei Yisrael or disregarded as soon as Yitzchak was born?
Answer: These people were and are the righteous non-Jews of the world. For example, there was Rachav who helped the Nation of Israel during the time of Yehoshua. They were not converted in the halachic sense since people - beside the Forefathers and Foremothers - could not become Jews during that time. Rabbi Tzadok Ha-Cohain of Lublin points out in his book "Takanat Ha-Shavim" that if this was not the cause than Yishmael and Esav would also have been Jewish. They therefore remain spread out among the world.
