I dupicated the layer, set the opacity to multiply and brought the percent down to ...... I think it was about 50%

Used a layer mask and the gradient set to black to transparent .... duplicated that layer about 3 times. In hindsight it could have had a few more, but .....
I basically fiddled around with levels and curves after that. I didn't do any repairs on the top left corner, so that could be made much more appealing. I did nothing with the mother and daughter either, so there are still lots of possibilities left to improve this more. I did crop the image to take away the majority of glare that was still in the top, left hand corner.
