Hi there, I am not sure of any decendents but I do have a Cushing Geneology. It is pretty beaten up but everything is still there and I don't mind looking anything up, I don't know how far back it goes or which Cushings it is relevant to but I do know it contains my great grandfather as the last mentioned person. I also have a world Cushing directory from a few years ago. Any questions feel free to contact me :)
