Names for foreign middle-class toffs

Also I do know/know of a couple of people called Milán, so not unheard of in the UK, but of course they may have Hungarian family that I don't know of.

Ooh what exciting names!
If he/she is going to grow up in the UK with a complicated surname, I would keep the first name short and simple. Then again, you could have what ever name you liked but use a simple nickname all the time perhaps eg Max, Nicky.

I would avoid Atilla and Zoltan I think.

Love all the girls' names though.

I would say use the native forms, definitely.

However: be prepared that the accents will probably be missed off most of the time (eg they will be written as Laszlo rather than László). If you mind this, then may be best to select a name without accents.

I would also suggest sticking to names which are pronounced roughly as they are spelled - which will make mispronunciation less likely.

I would also avoid Atilla as the main association for most English will be "Atilla the Hun".

If you are going to use the English forms, I would avoid Basil (associated with Fawlty Towers and Basil Brush - 1970s comedy TV characters)

My favourites, and I think reasonably easy for English tongues to pronounce, are:

Laszlo
Arpad
Miklos
Miksa (lovely name, but because it ends in an "a", people may assume it's a girl)
Xaver

Edua
Ilona

Oh and I don't think any of your list of names would have a "class" association in England.

I really like Maximilian. Think it's a fantastic name. Sorry for v brief post

I like Damira and Ilona.

Out of the boys ones - definitely not Atilla (totally associated here with Atilla the hun).

I like Miklos, Milan, Xavier, Miksa and Laszlo. You'd have to be prepared for the accents to be dropped though. I think Basil is a bit old fashioned in this country and associated with Basil Fawlty and Basil Brush. Geza is too much like 'geezer'.

TBH, I think that for the most part foreigners are excused the whole naming/class nonsense that goes on. I'd just pick the one you like the best and go with it . I think it's nice to use a name from your culture rather than Anglicising it, but that's just a matter of personal preference too really.

FWIW, I think that Maximilian and Julius both sound quite 'posh' in English (though not Max, which is a bit trendier atm).

From your list, I like Milán and Xavér the best for boys, and Ilona and Damira from your girl list, though I'm going purely on the way they sound to me - I don't know any of the meanings or connotations of them in Hungarian of course (or how they are pronounced!).

The only ones I think you might have problems with are Atilla (because of Atilla the Hun), Hunor (because it sounds very like Honor, which is a girls' name), likewise Gyula (if the G is soft, it sounds a bit like Julia?). And possibly Géza, depending on pronunciation, it might sound a bit like 'geezer' in English?

The only one of your names that I think would raise any eyebrows at all in their Hungarian form is Atilla (because of Atilla the Hun).

Basil and perhaps Julius are rather 'upper class' I would say in their English versions.
