I do understand Dave and naming the oldest son after dad (and granddad) is quite common here too. At birthdays it is not uncommon to have three generations of Piet's or Jan's in a room, but still we dont call ourselves the 2nd 3rd or umpteenth. And then there is that annoying middle initial thing. OK if you are a president maybe. Don't know. It might be just a harmless custom but it sound sooo pretentious to me. Might be because of a particular stuck-up character I met using both features in his name. Sorry ranting over again.
