A client wants to know, are there any earthbound lost souls from his mother losing or ending pregnancies still in need of help to reach the light?

This is not the case, and the reason is that the soul does not come down so very early and is largely beyond the fray during the span of time when such events take place, either the miscarriages or the termination of pregnancy deliberately. That is true for her and her losses. The events had some impact on souls still in the light but these had not come down and entered into earth plane fully and so were not at risk of being left in limbo. So this is a blessing for all concerned as it would add to potential negativity of the experience as a karmic legacy and burden but this has been avoided.
