Wikipeadia once I know a name. Read about the person and then look at/for more images of them. Follow the sites they are posted from, one thing leads to another rabbit hole and another and another.

I often have to use modifiers when I search. Like this lady. Margaret Hayes is a fairly common name although I found her name quickly. Then re-searched with actress (behind the name). Once I get some info it gets easier. Even her Dana Dale name got not much but put in Dana Dale model and bunches did.

I really do love learning about these entertainers that are mostly forgotten.

I have no knowledge about your computer skills, so forgive me if you already know how, but an image search is easy. Right-click on the image to bring up a menu, then click on 'search for this image using google lens'.
