I see names like Macdonald and MacDonald, where one family prefers the mid-capitalisation to another or family names like De Havilland. But it seems like a reasonable disambiguation to capitalise a family name.
Could you be more specific about what makes it "wrong".
FWIW my family name is commonly misspelt, life is too short to get too hung up about it. In my case it's just a name that existed prior to English standardisation.
In genealogical research it's typical to not only standardize capitalization of family names (typically to ALL CAPS) but to also standardize spelling to the most common or first used spelling. Otherwise searching becomes a very frustrating venture, and these things change surprisingly quickly through generations.
A long time back soundex [1] was used for matching things like names. I imagine there might be yet better algorithms these days but that one probably still solves this problem relatively well.
Would this not render fairly unambiguously to MAGUIDHIR (?spelling, corrected in an edit as I got it wildly wrong)? It only seems confusing if you're not Irish, and I'm already completely at sea with names that aren't Western European so this seems like a fine tradeoff to make.
But you're going to dreadfully confuse people looking for Mark McGwire (https://en.wikipedia.org/wiki/Mark_McGwire), for example. (And possibly "MacGuiver". I'm kind of unconvinced that it's related.)
wrong could be contrary to your preferred style. that's just how it goes. just because you don't care if others misspell you name doesn't mean that applies to all others.
I care, it's just it's an emotional response and over time I've realised that there's no real logical reason to correct it in most every situation. Of course people are not logical, and I don't expect others to share my values -- in part that's the point of asking question to get another perspective that I can use to alter my own.
