Just to be clear, I will restate it.
The problem with the arms provided by the published visitation is that they are in all likelihood a non-contemporary addition to the manuscript, and even if they were put there at the time it was compiled, there is no reason to think they are an authentic representation of the arms of Alexander, and a good reason to think they aren't - they appear to represent Percy and Lucy, a marriage that produced no children. As such, I think it would be a fool's errand to try to deduce a pedigree from this coat.
The Longstaffe coat is also problematic, in that he appears to be dating it to a heraldic display produced in the 17th century, too late to assume accuracy, and while the design matches the early Percy coat, the colours are different, which could represent a branch that had differenced the ancestral coat to distinguish their branch, or it could just be an error. I note that in another book Longstaffe is much more circumspect, saying these arms _probably_ intended to represent the Percy marriage, but that later illustrated renderings of it used the colours of the ancestral Percys and not the unique colourings of this coat. It is just all too wonky to take at face value, and unless you can find someone bearing the altered-colour coat independent of the Clervaux link, then it doesn't help anyhow.

Time machine?
Seriously, though, all you can do is dig through contemporary records and hope you turn up one that allows the Alexander associated with the Clervaux to be better identified, either by the naming of a relationship or an associated place name. I did a pretty thorough troll through Google Books and didn't turn up anything particularly useful, other than the Longstaffe sources.
