I got to your newsletter Gymnastics with Onomastics section when researching how I should state my given and family names in an application form in English (I am Brazilian). I had no knowledge of model languages and the amount of history, culture and information a language bears. It was rather interesting reading!

But the reason I'm writing is because you state that "English names are unique in one respect -- no other language has a construct similar to the Jr. (Junior) that gets appended to the names of boys who have the same names as their father's, so that Carl Glenn Henning's eponymous son is known as Carl Glenn Henning, Jr."

But in Brazilian Portuguese (I wouldn't know about Portugal) we do have a language construct such as English's "Jr." Some Brazilians append "Júnior" (or Jr.) to the name just like in English to note that the given name is the same as their father's. Moreover, others append "Neto" (meaning "grandchild") when using their grandfather's given name or even "Sobrinho" (meaning "nephew") for their uncle's. Another alternative form to "Júnior" is "Filho" (meaning "son"). All of this only applies to men and although this usage has been declining lately I do know some young people who bear this construct in their names.

Well, these are my "two cents worth"! Congratulations for the fine guide: it was interesting and very "readable" (not full of technicalities) even to someone who did not have any previous knowledge of the subject and was curious about it.
