How can I find records of my Jewish family who C*nverted out?

My family from my mother’s side were Mizrahi Jews who cnverted to Islam about 3/4 generations ago. Unfortunately, it’s much much harder finding records for mizrahim than Ashkenazim. All I know is that they were living in Morocco (not even sure where in Morocco) and then moved to Egypt and to the super tiny community that was once in Sudan (where they somehow mixed with Ethiopian Jews), most of them have unfortunately changed their names.

B”H I have returned and live a fully orthodox life now (after gi**yur obviously) but there’s a part of me that can never let this go. I tried looking up online and never found anything.
