I did. What little snippet is there appears to be hearsay from much later - and even at that, doesn’t carry your point even if it was true since any number of Christians including present company also believe in the truth of what is taught in Genesis. But the paper you provided had no more in the way of elaboration about how this alleged conversation unfolded.
Meanwhile, the paper I linked is extensively documented and includes many of Maxwell’s own words from his own correspondence. And from those it becomes quite apparent that he was no friend for science-deniers then and would not be now.
Newton, of course, would have had no reason to think in anything other than thousands of years age since he preceded the geology that was soon to challenge that.
And there may well be more to say about Faraday too, though, I would have to research that to know. But given what you have been fed about Maxwell (probably from Creationist publications that aren’t known for their veracity or full disclosure of relevant information) any such lists almost certainly need to be fact-checked.
And as Jim has already observed as well, their failure to be on board with newly developing (or even yet-to-be-developed) theories in other fields really does nothing to help the young-earther’s case. But even catering to the YEC desire to have a few historical “trophies”, they ought to at least see if the person actually thought that way.
