Pál, daughter of Daniel?
Yes, or a further descendant of Daniel’s daughter
Like Johnson is “John’s son” or their descendants
Iceland is (strongly?) patronymic. So this wouldn’t be talking about descendants, like in other languages where the patronym is fossilized as a family name, I believe. Only direct father or mother.
Cute cat tho
There’s a Free, Open-Source Software hotel!?
FOSS hotel is where RMS will reside when he goes on a vaca.
