Regicides?

We did have a letter/receipt somewhere with a translation that some ancient relative escaped England after the civil war and served in Hungary with a bunch of other royalists with not much else to do

That’s pretty neat. There were a number of English Catholics serving in the armies of France during the same period also.

I read somewhere that the number one export from Scotland in the 16/17th century was mercenaries and that they are the forebears of noble houses all over Europe.
