[Avodah] What happened to the nefesh asher asu b'charan?

[Rich, Joel]

Rashi states that Avraham and Sara were megayer many people. What
happened to these people? How come we don't hear anything about them?

I assume they "converted" to monotheism but didn't join their Rebbi for
a further trip(physical or spiritual)
Interesting question to me is could they have (byitchak yikarei...)
